NEW QUESTION # 47
(Which encryption mode is known for supporting parallel processing?)
Answer: D
Explanation:
ECB (Electronic Codebook) mode encrypts each block independently with the same key, which makes it naturally amenable to parallel processing: multiple blocks can be encrypted or decrypted simultaneously because there is no chaining dependency between blocks. This is in contrast to CBC encryption, where each plaintext block is XORed with the previous ciphertext block, creating a dependency that prevents straightforward parallelization of encryption (though CBC decryption can be parallelized because ciphertext blocks are already known). Feedback modes like CFB and OFB generate keystream material sequentially, where each step depends on the previous state, limiting parallelism. While ECB's parallelism is an implementation advantage, it is widely discouraged for most real data because it leaks patterns-identical plaintext blocks produce identical ciphertext blocks. Modern systems prefer parallel-friendly and secure modes such as CTR or GCM, but among the listed options, the mode most known for parallel processing is ECB due to block independence. Therefore, the correct answer is Electronic Codebook (ECB).
NEW QUESTION # 48
(Which of the following best describes lightweight cryptography?)
Answer: D
Explanation:
Lightweight cryptography refers to cryptographic primitives and profiles engineered for environments where computational resources are constrained-limited CPU, memory, power, bandwidth, and code size-while still requiring robust security. Typical targets include IoT sensors, embedded controllers, smart cards, RFID, wearables, and many mobile or edge deployments. The design goals emphasize efficiency (low energy consumption, small silicon area for hardware, small firmware footprint) and practical performance under constraints, often while providing modern security properties like authenticated encryption (confidentiality + integrity) and secure hashing. Lightweight cryptography is not simply "stronger encryption"; it balances security with implementability in constrained systems. It is also not restricted to military settings and is not inherently outdated-many lightweight designs are modern and motivated by the rapid growth of IoT and pervasive computing. Because constrained devices are common entry points for attackers, having secure primitives that fit those devices is a critical part of contemporary security architecture. Therefore, the best description is cryptographic algorithms designed for resource-constrained environments.
NEW QUESTION # 49
(What is the purpose of code-signing in current systems?)
Answer: D
Explanation:
Code-signing is used to provide verifiable assurance that software comes from a known publisher and has not been modified since it was signed. In a typical code-signing workflow, the publisher computes a cryptographic hash (digest) of the executable or package and then creates a digital signature over that digest using the publisher's private key. Operating systems, browsers, and application platforms verify the signature using the corresponding public key (usually delivered via a code-signing certificate chained to a trusted root).
If verification succeeds, the system can trust that the code's contents match what the publisher signed (integrity) and that the signer identity is authenticated by the certificate chain (authenticity). This helps defend against tampering, malware injection, and supply-chain attacks where attackers alter binaries or updates in transit or at rest. Code-signing does not primarily generate randomness, compress data, or authenticate users; it authenticates the software publisher and validates the software artifact. Modern ecosystems also use timestamping and revocation checking to handle certificate expiration and compromised signing keys, reinforcing trust over time.
NEW QUESTION # 50
(Which type of encryption is Advanced Encryption Standard (AES) considered to be?)
Answer: D
Explanation:
AES is a symmetric-key block cipher, meaning the same shared secret key is used for both encryption and decryption. It operates on fixed-size 128-bit blocks and supports key sizes of 128, 192, and 256 bits. Being symmetric, AES is efficient and well-suited for encrypting large volumes of data-files, disk encryption, VPN payloads, and bulk traffic in protocols like TLS once a session key is established. AES is not "hybrid" by itself; hybrid encryption refers to combining asymmetric cryptography (for key exchange or key wrapping) with symmetric cryptography (for bulk data encryption), and AES often plays the symmetric part of that hybrid design. It is not "quantum encryption," which is a separate, loosely used term sometimes referring to quantum key distribution or quantum-resistant algorithms. AES is also not asymmetric; it does not use public
/private key pairs. Therefore, AES is correctly classified as symmetric encryption, matching option D.
NEW QUESTION # 51
(What are the primary characteristics of Bitcoin proof of work?)
Answer: D
Explanation:
Bitcoin's proof of work (PoW) is designed so that finding a valid block is computationally difficult, but checking validity is computationally easy. Miners must repeatedly hash candidate block headers (double SHA-
256) with different nonces until they find a hash value below a network-defined target. This trial-and-error search requires significant work and energy because the probability of success per attempt is extremely low at current difficulty levels. However, verification is straightforward: any node can hash the block header once (or a small number of times) and confirm the resulting hash meets the target threshold and that the block contents follow protocol rules. This "hard to produce, easy to verify" property is essential: it makes it expensive for attackers to rewrite history or outpace honest miners, while allowing all participants-even low- power devices-to validate blocks efficiently. Therefore, the primary characteristic of Bitcoin proof of work is that it is difficult to produce and easy to verify.
