NEW QUESTION # 58
(What is a focus of the ISO/IEC 27001 standard?)
Answer: B
Explanation:
ISO/IEC 27001 is an international standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). Its focus is not inventing cryptographic algorithms, but managing information security through a structured governance approach: identifying assets, assessing risks, selecting and implementing controls, measuring effectiveness, and continuously improving.
The standard emphasizes a risk-based methodology-controls are chosen based on organizational context and threat landscape, and the ISMS is refined over time through audits, management reviews, and corrective actions. While cryptography can be part of the control set (e.g., encryption policies, key management, secure communications), ISO/IEC 27001 addresses a broad range of security domains beyond crypto, including physical security, access control, incident management, supplier relationships, and business continuity. It also does not enforce criminal penalties; it is a certification/management standard. And it is not limited to network security. Therefore, the correct focus is risk management and continuous improvement of information security.
NEW QUESTION # 59
(What is the maximum key size (in bits) supported by AES?)
Answer: B
Explanation:
AES supports three standardized key sizes: 128, 192, and 256 bits, with a fixed block size of 128 bits.
The maximum of these supported key sizes is 256 bits (AES-256). Key size affects resistance to brute- force key search: larger keys exponentially increase the search space. In practice, AES-128 is already considered strong against brute force with contemporary computing capabilities, while AES-256 is often chosen for compliance requirements, conservative security margins, or to hedge against future advances. AES-512 is not part of the AES standard; if 512-bit keys are desired, systems typically use different constructions (like using AES-256 in certain key-derivation or wrapping schemes) rather than changing AES itself. Therefore, the correct maximum supported AES key size is 256 bits.
NEW QUESTION # 60
(What describes how Counter (CTR) mode encryption functions?)
Answer: A
Explanation:
CTR mode turns a block cipher (like AES) into a stream-like construction by generating a keystream from successive encryptions of a changing input block. Specifically, CTR forms input blocks using a nonce (unique per message) combined with an increasing counter. Each nonce||counter block is encrypted with the block cipher under the shared key, producing a pseudorandom output block. That output is then XORed with plaintext to yield ciphertext (and XORed with ciphertext to recover plaintext). This design enables parallelization (blocks can be generated independently), efficient random access decryption, and avoids chaining dependencies seen in modes like CBC. Option B describes CFB-like behavior; option C describes ECB; option D describes CBC. CTR's security critically depends on never reusing the same nonce/counter sequence with the same key, because reuse would repeat keystream blocks and expose plaintext relationships.
Therefore, the correct description is that CTR converts the block cipher into a stream cipher using a counter value and a nonce.
NEW QUESTION # 61
(Which cipher uses shifting letters of the alphabet for encryption?)
Answer: C
Explanation:
The Caesar cipher is the classic substitution cipher that encrypts by shifting letters of the alphabet by a fixed number of positions (e.g., shift by 3: A#D, B#E, etc.). It is a monoalphabetic cipher because a single shift value is applied uniformly across the entire message, making it simple and vulnerable to frequency analysis and brute force (only 25 meaningful shifts in the Latin alphabet). Vigenere also involves shifting, but it uses a repeating keyword to vary the shift per character (polyalphabetic), whereas the question's phrasing typically points to the fundamental "shift cipher," which is Caesar.
SHA-1 is a cryptographic hash function, not a cipher. Bifid is a fractionation cipher combining Polybius square coordinates and transposition, not a direct shifting method. Therefore, the cipher that uses shifting letters of the alphabet for encryption is the Caesar cipher.
NEW QUESTION # 62
(Which mode of encryption uses an Initialization Vector (IV) to encrypt the first block and then uses the result to encrypt the next block?)
Answer: D
Explanation:
CBC mode introduces dependency between blocks to prevent the pattern leakage seen in ECB. It starts with a random (or unpredictable) IV for the first block. Before encrypting block 1, CBC XORs plaintext block 1 with the IV, then encrypts the result. For block 2 and onward, CBC XORs each plaintext block with the previous ciphertext block before encryption. This chaining means that changing one plaintext block affects that block's ciphertext and also influences the next block's computation. The IV ensures that encrypting the same message twice under the same key produces different ciphertexts (assuming a fresh IV). Option A (ECB) has no IV or chaining. OFB and CFB are feedback modes that effectively generate a keystream; they do use an IV, but the "uses the result to encrypt the next block" wording most directly matches CBC's ciphertext-chaining description in standard teaching. CBC still requires integrity protection (e.g., HMAC or an AEAD mode) because it can be malleable without authentication. Therefore, the correct mode is Cipher Block Chaining (CBC).
