NEW QUESTION # 43
(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: A
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).
NEW QUESTION # 44
(Which of the following is an example of a software encryption solution for disk storage?)
Answer: B
Explanation:
Disk/storage encryption protects data at rest by encrypting the contents of a drive so it remains unreadable without the correct authentication and keys. BitLocker (commonly on Windows) and FileVault (commonly on macOS) are well-known software-based full-disk encryption solutions integrated into their operating systems.
They encrypt sectors on disk and typically tie key protection to user credentials and, where available, hardware features such as a TPM or secure enclave to reduce key extraction risk. A VPN encrypts network traffic in transit, not disk storage. An HSM is specialized hardware used to generate, store, and protect cryptographic keys and perform crypto operations; it is not a disk encryption product itself. USB encryption hardware refers to hardware-encrypted removable media, not a software solution for a system disk. Therefore, the correct example of a software encryption solution for disk storage is BitLocker and FileVault.
NEW QUESTION # 45
(Why is it important for cryptography frameworks to adapt over time?)
Answer: A
Explanation:
Cryptography must evolve because threats, computing capabilities, and attack techniques continuously change. Algorithms once considered safe can become vulnerable due to cryptanalysis, implementation attacks, protocol flaws, or sheer increases in available compute power. Examples include the deprecation of SHA-1 for signatures, weakening of RC4, and migration away from older TLS versions and weak cipher suites. Frameworks also need to adapt to new environments-cloud architectures, IoT deployments, mobile devices-and new adversary models, including the long-term risk posed by quantum computing to current public-key systems. Adaptation includes updating standards, increasing key sizes where needed, adopting modern primitives (AEAD modes, stronger KDFs), improving key management practices (rotation, hardware- backed storage), and refining operational guidance (certificate lifetimes, revocation strategies). A rigid structure that never changes would lock organizations into obsolete protections and accumulate risk.
Standardizing obsolete techniques or complying with outdated standards is the opposite of sound security engineering. Therefore, cryptography frameworks must adapt over time to respond to emerging threats and vulnerabilities and to maintain effective protection as the landscape evolves.
NEW QUESTION # 46
(Which encryption algorithm encrypts with one key, decrypts with another key, and then encrypts with the first key?)
Answer: B
Explanation:
3DES (Triple DES) commonly uses an Encrypt-Decrypt-Encrypt (EDE) sequence. In the two-key form, it encrypts with key K1, decrypts with key K2, then encrypts again with K1. In the three-key form, it encrypts with K1, decrypts with K2, then encrypts with K3. The EDE construction was chosen partly for backward compatibility: if K1=K2=K3, the scheme reduces to single DES, allowing older systems to interoperate in constrained ways. AES and IDEA do not use an EDE triple-stage process as their defining structure; they are single-pass block ciphers with internal rounds. DES is a single-pass algorithm (one key) rather than a triple application with multiple keys. Therefore, the algorithm described-encrypt with one key, decrypt with another, encrypt with the first-is 3DES. Although now considered legacy, it remains a classic example of increasing effective security by applying a block cipher multiple times with independent keys.
NEW QUESTION # 47
(What is a component of a one-time password (OTP) that is needed to guess future iterations of passwords?)
Answer: B
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.
