NEW QUESTION # 39
(Which cryptographic technique is used to ensure data integrity?)
- A. Steganography
- B. Digital signatures
- C. Authentication
- D. Non-repudiation
Answer: B
Explanation:
Data integrity means ensuring that information has not been modified without authorization. Digital signatures are a core cryptographic technique that provides integrity by binding a message (typically its hash) to the signer's private key. The signer creates a signature over the message digest; the verifier checks it with the signer's public key and recomputes the digest. Any change to the message alters the digest and causes verification to fail, revealing tampering. Digital signatures also support authenticity (verifying the signer) and can contribute to nonrepudiation under proper key-management and policy controls, but integrity is a primary guarantee they deliver. "Authentication" is broader and can be achieved by other means, but it is not as directly tied to integrity as signatures in this option set. "Non-repudiation" is an outcome/goal rather than a standalone integrity technique. "Steganography" hides the existence of data and does not inherently protect integrity. Therefore, among these options, digital signatures are the best cryptographic technique for ensuring data integrity.
NEW QUESTION # 40
(Why is lightweight cryptography important in modern information security?)
- A. To complicate data protection measures
- B. To ensure secure communication on high-speed networks
- C. To limit the use of encryption tools in organizations
- D. To address the security needs of Internet of Things (IoT) devices and mobile applications
Answer: D
Explanation:
Lightweight cryptography is important because many modern systems operate in constrained environments- IoT sensors, embedded controllers, wearables, and mobile devices-where CPU, memory, storage, bandwidth, and battery power are limited. Traditional "heavy" cryptographic suites may be too slow, too energy-intensive, or too large in code footprint for these platforms, leading to insecure workarounds or disabling security entirely. Lightweight cryptographic primitives and profiles are designed to deliver strong security properties (confidentiality and integrity, often via AEAD) while fitting within tight resource budgets and real-time constraints. This is essential as IoT and mobile ecosystems expand, increasing the attack surface and the consequences of compromised devices (botnets, surveillance, physical safety risks). Lightweight cryptography is not meant to "limit encryption tools" or complicate protection; it enables practical, deployable security where otherwise implementations might be weak or absent. High-speed network communication can benefit from efficient crypto too, but the defining modern driver is constrained-device security. Therefore, the correct reason is addressing the security needs of IoT devices and mobile applications.
NEW QUESTION # 41
(How does adding salt to a password improve security?)
- A. Salt enforces the complexity rules for passwords.
- B. Salt ensures two people do not have the same password.
- C. Salt creates a different hash if two people use the same password.
- D. Salt prevents users from reusing the same password.
Answer: C
Explanation:
A salt is a unique, random value stored alongside a password hash and combined with the password during hashing. Its main security benefit is that it ensures identical passwords do not produce identical hashes across different accounts or systems. If two users choose the same password, their stored hashes will differ because their salts differ, which directly prevents attackers from spotting shared passwords by comparing hashes. Salts also defeat precomputation attacks such as rainbow tables, because an attacker would need to regenerate tables for each possible salt value-a task that becomes infeasible when salts are large and unique per password. Salt does not enforce password complexity rules (that's a policy/validation function), does not guarantee users choose different passwords, and does not prevent password reuse across sites. The correct statement is that salt makes the resulting hash different even for the same password, improving resistance to offline cracking at scale and eliminating the "same hash
= same password" shortcut attackers rely on.
NEW QUESTION # 42
(What is the value of 51 mod 11?)
- A. 07
- B. 0
- C. 04
- D. 05
Answer: A
Explanation:
The value 51 mod 11 is the remainder after dividing 51 by 11. Modular arithmetic is widely used in cryptography to keep computations within a finite set of residues, such as in RSA where values are taken modulo n, or in Diffie-Hellman where exponents and group elements are reduced modulo a prime. To compute 51 mod 11, find the largest multiple of 11 less than or equal to 51. Multiples of 11 are 11, 22, 33, 44,
55. The closest without exceeding 51 is 44. Subtracting gives 51 # 44 = 7, so the remainder is 7. Therefore, 51 mod 11 = 7, matching option "07." This remainder is always in the range 0 through 10 because the modulus is
11. Such residue computations underpin the "wraparound" behavior that makes modular exponentiation and inverse computations well-defined in cryptographic groups.
NEW QUESTION # 43
(What is the correlation between the number of rounds and the key length used in the AES algorithm?)
- A. The number of rounds is the same regardless of the key length.
- B. The number of rounds increases as the key length increases.
- C. The key length is the same regardless of the number of rounds.
- D. The number of rounds decreases as the key length increases.
Answer: B
Explanation:
In AES, the number of rounds is explicitly tied to the key length. AES-128 uses 10 rounds, AES-192 uses 12 rounds, and AES-256 uses 14 rounds. The purpose of additional rounds is to increase diffusion and confusion, strengthening resistance against cryptanalysis as the key schedule and state transformations iterate more times. Although key length primarily affects brute-force resistance, AES's designers and standardization parameters link longer keys with more rounds to maintain security margins across variants, especially considering differences in the key schedule structure. Thus, as key length increases from 128 to 192 to 256 bits, the number of rounds increases correspondingly from 10 to 12 to 14. This relationship is fixed by the AES specification and does not vary dynamically at runtime. Therefore, the correct correlation is that the number of rounds increases as the key length increases.
NEW QUESTION # 44
(Which symmetric encryption technique uses a 112-bit key size and a 64-bit block size?)
- A. AES
- B. 3DES
- C. DES
- D. IDEA
Answer: B
Explanation:
3DES (Triple DES) is a symmetric block cipher that retains DES's 64-bit block size while increasing effective security by applying DES multiple times. The common "two-key 3DES" variant uses two independent 56-bit DES keys (K1 and K2) in an Encrypt-Decrypt-Encrypt (EDE) sequence: Encrypt with K1, Decrypt with K2, then Encrypt again with K1. Because each DES key is 56 bits (ignoring parity bits), the total keying material is 112 bits. This matches the question's "112-bit key size and 64- bit block size." Plain DES uses only a 56-bit effective key and a 64-bit block size, so it does not match the 112-bit key size. AES has a 128-bit block size and key sizes of 128/192/256. IDEA uses a 64-bit block size but has a 128-bit key. Therefore, the correct algorithm is 3DES. Although 3DES improved on DES, it is now considered legacy due to its small 64-bit block size (birthday-bound issues for large data volumes) and performance overhead compared to AES.
NEW QUESTION # 45
(What are the roles of keys when using digital signatures?)
- A. A public key is used for signing, and a private key is used for signature validation.
- B. A private key is used for signing, and a public key is used for signature validation.
- C. A private key is used for both signing and signature validation.
- D. A public key is used for both signing and signature validation.
Answer: B
Explanation:
Digital signatures provide integrity, authenticity, and typically non-repudiation by using an asymmetric key pair. The signer uses the private key to create a signature over a message (usually over a hash/digest of the message). Because the private key is kept secret, only the legitimate signer should be able to produce a valid signature. Anyone who has the corresponding public key can then validate the signature: they verify that the signature matches the message digest under the public key and that the signed data has not been altered. This is why the public key can be widely distributed (often inside an X.509 certificate) while the private key must be protected by the signer. If a public key were used to sign, anyone could forge signatures; if a private key were required for validation, only the signer could validate, defeating the purpose of public verifiability.
Therefore, the correct key roles are private key for signing and public key for signature validation.
NEW QUESTION # 46
(Which wireless security standard uses an authentication server with 802.1X and EAP?)
- A. WPA-PSK
- B. WEP
- C. TKIP
- D. WPA-Enterprise
Answer: D
Explanation:
802.1X is a port-based network access control framework that enables centralized authentication using an authentication server (commonly RADIUS). EAP (Extensible Authentication Protocol) runs within
802.1X to support many credential types (password-based methods like PEAP, certificate-based methods like EAP-TLS, and others). WPA-Enterprise is the wireless security mode that explicitly uses
802.1X + EAP with an authentication server to perform per-user/per-device authentication and to derive dynamic session keys. By contrast, WPA-PSK uses a pre-shared key without an external authentication server; all users share the same PSK, which is weaker for enterprise identity management. WEP is an older mechanism using static keys and does not provide modern 802.1X/EAP enterprise authentication in the WPA-Enterprise sense. TKIP is an encryption/integrity protocol used under WPA, not the full authentication "standard" involving an authentication server. Therefore, the correct choice is WPA-Enterprise.
NEW QUESTION # 47
(Two people want to communicate through secure email. The person creating the email wants to ensure only their friend can decrypt the email. Which key should the person creating the email use to encrypt the message?)
- A. Sender's private key
- B. Recipient's private key
- C. Sender's public key
- D. Recipient's public key
Answer: D
Explanation:
To ensure confidentiality so that only the intended recipient can decrypt an email, the sender must encrypt in a way that only the recipient can reverse. In public key cryptography, that means encrypting with the recipient's public key. The recipient is the only party who should possess the matching private key, so only they can decrypt the ciphertext. This pattern is fundamental to PKI-based secure email systems such as S/MIME and OpenPGP: the sender looks up or is provided the recipient's certificate/public key, encrypts the message (often by encrypting a randomly generated symmetric session key with the recipient's public key), and the recipient uses their private key to recover the session key and decrypt the content. Encrypting with the sender' s private key would not provide confidentiality; it resembles signing because anyone with the sender's public key could "decrypt" it. Encrypting with a private key of the recipient is also incorrect because private keys are not shared and should never leave the recipient's control. Therefore, the correct key to encrypt the message so only the friend can decrypt it is the recipient's public key.
NEW QUESTION # 48
(Which number generator has different results given the same input data?)
- A. Pseudorandom
- B. True random
- C. Prime
- D. Sequence
Answer: B
Explanation:
A true random number generator (TRNG) produces outputs derived from nondeterministic physical processes (e.g., thermal noise, oscillator jitter, radioactive decay, or other hardware entropy sources). Because the underlying phenomenon is not algorithmically determined by an input seed in the same way as a PRNG, repeated "inputs" (or identical conditions from a software perspective) do not yield the same sequence; the outputs vary unpredictably. By contrast, a pseudorandom number generator (PRNG) is deterministic: given the same seed and internal state, it produces the same output sequence, which is useful for repeatability but means security depends on seed secrecy and proper seeding. "Prime" is not a generator type, and "sequence" is too generic and does not imply nondeterminism. In cryptographic systems, TRNGs (or hardware entropy sources) are often used to seed cryptographically secure PRNGs (CSPRNGs), combining high-quality entropy with efficient generation. Therefore, the generator that can produce different results for the "same input data" is a true random number generator.
NEW QUESTION # 49
(Which mechanism can be applied to protect the integrity of plaintext when using AES?)
- A. RSA
- B. Message Authentication Code (MAC)
- C. Kerberos key sharing
- D. RC4
Answer: B
Explanation:
AES by itself is a symmetric block cipher that provides confidentiality, but not guaranteed integrity unless used in an authenticated mode. To protect integrity of the plaintext (ensuring it has not been altered), a Message Authentication Code (MAC) can be applied. In the classic Encrypt-then-MAC pattern, the sender encrypts the plaintext with AES and then computes a MAC (often HMAC-SHA-256 or CMAC-AES) over the ciphertext (and relevant headers). The receiver verifies the MAC before attempting decryption, preventing tampering and many padding-oracle style vulnerabilities.
Alternatively, AES can be used in an AEAD mode like AES-GCM, which produces an authentication tag serving a similar purpose, but among the listed options the general integrity mechanism is "MAC." RC4 is an unrelated stream cipher and does not provide integrity. RSA is asymmetric and not the standard integrity add-on for AES-encrypted bulk data. Kerberos is an authentication protocol and key distribution system, not a message integrity primitive. Therefore, to protect plaintext integrity when using AES, the correct mechanism is a Message Authentication Code.
NEW QUESTION # 50
(Which component is used to verify the integrity of a message?)
- A. AES
- B. IV
- C. TKIP
- D. HMAC
Answer: D
Explanation:
HMAC (Hash-based Message Authentication Code) is a standard mechanism used to verify both integrity and authenticity of a message when two parties share a secret key. It combines a cryptographic hash function (such as SHA-256) with a secret key in a structured way that resists common attacks on naive keyed-hash constructions. The sender computes an HMAC tag over the message and transmits the message plus tag. The receiver recomputes the HMAC using the same shared secret key and compares the result; if the tag matches, the receiver can be confident the message was not modified in transit and that it came from someone who knows the shared key. AES is an encryption algorithm primarily providing confidentiality; it can provide integrity only when used in authenticated modes (e.g., GCM) but "AES" alone is not the integrity component. An IV helps randomize encryption but does not validate integrity. TKIP is a legacy WLAN protocol component, not the general integrity verifier. Therefore, the correct component for verifying message integrity among the options is HMAC.
NEW QUESTION # 51
(How can auditing enhance an organization ' s cryptographic practices?)
- A. It identifies weaknesses in current practices.
- B. It guarantees that no security incidents will occur.
- C. It ensures all employees are trained in cryptography.
- D. It eliminates the need for regular policy updates.
Answer: A
NEW QUESTION # 52
(Which symmetric encryption technique uses a 256-bit key size and a 128-bit block size?)
- A. 3DES
- B. DES
- C. AES
- D. IDEA
Answer: C
Explanation:
AES (Advanced Encryption Standard) is a symmetric block cipher standardized to operate on a fixed
128-bit block size and supports key sizes of 128, 192, and 256 bits. When the key size is 256 bits, the cipher is commonly referred to as AES-256, but the block size remains 128 bits regardless of key length.
This combination (256-bit key, 128-bit block) matches the question precisely. By comparison, DES uses a 64-bit block size with a 56-bit effective key. 3DES also uses a 64-bit block size and effectively applies DES three times, yielding an effective key length typically cited as 112 bits (two-key 3DES) or 168 bits (three-key 3DES), depending on how keys are configured. IDEA uses a 64-bit block size with a 128-bit key. Therefore, the only listed algorithm that supports a 256-bit key while maintaining a 128-bit block size is AES. This is one reason AES is widely adopted for modern symmetric encryption: strong key sizes with efficient implementation and broad standardization.
NEW QUESTION # 53
(Which is an example of asymmetric encryption?)
- A. Elliptic-Curve Cryptography (ECC)
- B. Hash-based Message Authentication Code (HMAC)
- C. Secure Hash Algorithm 256 (SHA-256)
- D. Data Encryption Standard (DES)
Answer: A
Explanation:
Asymmetric cryptography uses a public/private key pair where different keys are used for related operations (encryption/decryption or signature/verification). Elliptic-Curve Cryptography (ECC) is a family of asymmetric algorithms built on the mathematics of elliptic curves over finite fields. ECC supports key exchange (ECDH), digital signatures (ECDSA/EdDSA), and other primitives with smaller key sizes for comparable security to traditional discrete-log or RSA systems (e.g., a 256-bit ECC key is often comparable in security to a 3072-bit RSA key, depending on scheme and parameters). By contrast, SHA-256 is a cryptographic hash function (one-way digest), and HMAC is a keyed integrity/authentication construction built from a hash function-neither is encryption. DES is a symmetric block cipher (same key for encryption and decryption). Therefore, the example of asymmetric encryption among the options is ECC.
NEW QUESTION # 54
(What is the Enigma machine known for in the history of cryptography?)
- A. A method for decrypting messages
- B. A software program for encrypting emails
- C. A device used for secure communication during World War II
- D. A type of cryptographic algorithm
Answer: C
Explanation:
The Enigma machine is historically known as an electro-mechanical cipher device used primarily by Nazi Germany to secure military and diplomatic communications during World War II. It implemented a polyalphabetic substitution through a system of rotors, a reflector, and a plugboard, producing a large number of possible daily key settings. Operators would configure rotor order, ring settings, initial positions, and plugboard swaps, then type messages to generate ciphertext. Enigma's operational security depended heavily on correct procedures and secrecy of keys; weaknesses in procedures and design properties, combined with brilliant cryptanalysis and engineering efforts by Allied codebreakers (notably at Bletchley Park), enabled large-scale decryption of Enigma-encrypted traffic. In cryptography history, Enigma represents the transition from manual ciphers to machine-assisted encryption and demonstrates how both mathematics and operational practices determine real-world security. It is not simply an "algorithm" in the modern software sense, and it is not a decryption method or email encryption tool. Therefore, the correct description is that it was a device used for secure communication during WWII.
NEW QUESTION # 55
(Which attack may take the longest amount of time to achieve success?)
- A. Rainbow table
- B. Brute-force
- C. Dictionary
- D. Birthday
Answer: B
Explanation:
A brute-force attack exhaustively tries every possible key or password candidate until the correct one is found. Because it explores the full search space (or a very large portion of it), brute force is often the slowest method, especially when strong keys, long passwords, rate limits, and slow password hashing (bcrypt/Argon2) are used. By contrast, a dictionary attack reduces work by trying only common or likely passwords, often succeeding quickly against weak human-chosen secrets. Rainbow table attacks shift work into precomputation; once a table exists, lookup can be faster than brute-force-though salt and modern hashing defeat them. Birthday attacks are about finding collisions, not necessarily recovering a specific secret, and their expected work is about 2^(n/2) for an n-bit hash, which can be less than brute-force key search in many contexts. Therefore, among the listed options, brute-force generally takes the longest to succeed because it makes the fewest assumptions and does the most total work.
NEW QUESTION # 56
(Which mode of encryption converts data into a stream encryption and then uses a counter value and a nonce to encrypt the data?)
- A. Counter (CTR)
- B. Electronic Codebook (ECB)
- C. Cipher Block Chaining (CBC)
- D. Cipher Feedback (CFB)
Answer: A
Explanation:
CTR (Counter) mode converts a block cipher into a stream-like encryption method by generating a keystream from encrypted counter blocks. The core idea is to construct a sequence of input blocks using a nonce (unique per message/session) plus an incrementing counter. Each nonce||counter block is encrypted with the block cipher under the shared key; the output is a pseudorandom block that is XORed with plaintext to produce ciphertext. Decryption repeats the same keystream generation and XORs with ciphertext to recover plaintext.
CTR offers practical benefits: it is highly parallelizable, supports precomputation of keystream blocks, and allows random access to any block without needing previous blocks (unlike CBC). ECB and CBC are block modes that do not use nonce+counter keystream generation. CFB is a feedback mode that can behave stream- like, but it does not use the explicit counter/nonce construction characteristic of CTR. CTR's security hinges on never reusing the same nonce/counter sequence with the same key, because that would reuse the keystream and enable XOR-based plaintext recovery. Therefore, the correct mode is Counter (CTR).
NEW QUESTION # 57
(Which authentication method allows a web service installed on a network operating system to prove its identity to a customer?)
- A. One-way client authentication
- B. End-to-end authentication
- C. Mutual authentication
- D. One-way server authentication
Answer: D
Explanation:
One-way server authentication is the standard model used by most TLS-enabled web services to prove the server's identity to a client. In this model, the server presents an X.509 certificate during the TLS handshake. The client validates the certificate chain to a trusted root CA, checks hostname binding (CN
/SAN), validates validity dates, and may check revocation status. If validation succeeds, the client gains cryptographic assurance that it is communicating with the holder of the private key corresponding to the server certificate's public key, and that the certificate is issued to the expected domain/identity. This proves the server's identity to the customer without requiring the customer to present a certificate.
Mutual authentication would require both client and server to authenticate each other using certificates (commonly in certain enterprise APIs), but the question asks specifically about the web service proving its identity to the customer, which is satisfied by server-only authentication. One-way client authentication is the opposite direction (client proves identity to server). "End-to-end authentication" is a broader concept and not the specific TLS identity proof mechanism described here. Thus, one-way server authentication is the correct choice.
NEW QUESTION # 58
(Which mechanism implemented in WPA-Enterprise guards against bit-flipping exploits?)
- A. Pre-shared key (PSK)
- B. Advanced Encryption Standard (AES)
- C. Message Integrity Check (MIC)
- D. Global encryption key
Answer: C
Explanation:
Bit-flipping exploits target encryption modes or protocols that do not provide strong integrity, allowing attackers to modify ciphertext so that predictable changes occur in plaintext after decryption. To defend against this, protocols add an integrity mechanism that detects tampering. In WPA (including enterprise deployments), TKIP introduced a Message Integrity Check (MIC) called "Michael." The MIC is computed over the frame contents (with additional fields) and verified by the receiver; if an attacker flips bits in transit, the MIC verification fails, and the frame is rejected. While AES (used by WPA2's CCMP) also provides integrity via authenticated encryption, the option presented that directly names the tamper-detection mechanism associated with guarding against bit-flipping is MIC. A pre- shared key is an authentication/keying method (and not enterprise-mode anyway), and a "global encryption key" would be the opposite of what you want-global/static keys worsen security.
Therefore, the intended mechanism that mitigates bit-flipping by detecting unauthorized modifications is the Message Integrity Check.
NEW QUESTION # 59
(What is a component of a one-time password (OTP) that is needed to guess future iterations of passwords?)
- A. Initialization vector
- B. Function
- C. Seed
- D. Encryption algorithm
Answer: C
Explanation:
OTP systems (such as HOTP and TOTP) generate a sequence of passwords using a shared secret and a moving factor (counter or time). The critical secret that underpins the ability to compute past or future OTP values is the seed (also called the shared secret key). In HOTP, the seed is used with an HMAC function and an incrementing counter; in TOTP, the seed is used with HMAC and a time-step value. If an attacker obtains the seed and knows the algorithm and moving factor, they can compute future OTPs. The "function" and
"encryption algorithm" are typically standardized and public; security relies on keeping the seed secret. An initialization vector is not a standard OTP component in HOTP/TOTP generation. Therefore, the component needed to predict future OTP values is the seed. Protecting the seed is essential: it should be stored securely (e.
g., hardware token secure storage) and transmitted only through controlled provisioning processes. If compromised, OTP becomes predictable and no longer serves as a strong second factor.
NEW QUESTION # 60
(What is the correlation between the number of rounds and the key length used in the AES algorithm?)
- A. The number of rounds is the same regardless of the key length.
- B. The number of rounds increases as the key length increases.
- C. The key length is the same regardless of the number of rounds.
- D. The number of rounds decreases as the key length increases.
Answer: B
Explanation:
In AES, the number of rounds is explicitly tied to the key length. AES-128 uses 10 rounds, AES-192 uses 12 rounds, and AES-256 uses 14 rounds. The purpose of additional rounds is to increase diffusion and confusion, strengthening resistance against cryptanalysis as the key schedule and state transformations iterate more times. Although key length primarily affects brute-force resistance, AES's designers and standardization parameters link longer keys with more rounds to maintain security margins across variants, especially considering differences in the key schedule structure. Thus, as key length increases from 128 to 192 to 256 bits, the number of rounds increases correspondingly from 10 to
12 to 14. This relationship is fixed by the AES specification and does not vary dynamically at runtime.
Therefore, the correct correlation is that the number of rounds increases as the key length increases.
NEW QUESTION # 61
(What is the length (in bits) of a SHA-1 hash output?)
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
SHA-1 (Secure Hash Algorithm 1) produces a fixed-size output of 160 bits (20 bytes). Hash output size matters in cryptography because it influences collision resistance and the effort required for various attacks.
For an ideal n-bit hash, finding a collision by generic means is expected around 2^(n/2) operations (birthday bound). With SHA-1's 160-bit output, that generic bound would be about 2^80, which was once considered strong; however, SHA-1 has been broken in practice with significantly less work due to cryptanalytic advances, and it is now deprecated for most security uses. Still, the question is strictly about output length, not current suitability. The other options do not match SHA-1: 40 bits would be far too small for a modern hash,
80 bits is not SHA-1's output, and 320 bits would imply a much larger digest (closer to SHA-256's 256 bits or SHA-384's 384 bits). Therefore, the correct SHA-1 output length is 160 bits.

NEW QUESTION # 63
(Which operation can be performed on a certificate during the "Issued" stage?)
- A. Key recovery
- B. Creation
- C. Key archiving
- D. Distribution
Answer: D
Explanation:
The "Issued" stage in a certificate lifecycle indicates that the certificate has been generated and signed by the issuing CA and is now valid for use (subject to validity dates, policy constraints, and revocation status). At this point, the operational focus shifts from creating the certificate to making it available to the subject and relying parties. "Distribution" is the lifecycle activity most directly associated with an issued certificate: installing it on servers or endpoints, provisioning it into keystores, publishing it to directories if required, and ensuring the chain (intermediates) is accessible for validation. By contrast,
"Creation" is earlier in the process (key generation, CSR creation, identity validation, issuance
/signing). "Key recovery" and "key archiving" relate to private key management and escrow policies (often for encryption keys, not signing keys), and are governed by organizational policy and key management systems rather than the certificate's issued state itself. A certificate can be distributed after issuance regardless of whether any key escrow features exist. Therefore, the operation that fits the certificate's "Issued" stage best is distribution of the issued credential for operational use.
