NEW QUESTION # 64
(What describes a true random number generator?)
Answer: B
Explanation:
A true random number generator (TRNG) draws randomness from physical phenomena that are inherently unpredictable and not algorithmically reproducible. Because of this, it is nondeterministic: you cannot feed it the same "input" and expect the same output stream. TRNGs are often slower than PRNGs because they depend on collecting entropy from hardware sources and may require conditioning to remove bias. This aligns with option B: slow and nondeterministic, producing different results even under similar or repeated conditions. Option A describes a deterministic PRNG, where identical seeds yield identical sequences. Option C is unrelated; factorization is a hard math problem used in cryptography (e.g., RSA security assumptions), not a randomness generator definition. Option D describes a counter, which is deterministic and not random.
In secure systems, TRNG output may seed a cryptographically secure PRNG to provide both unpredictability and high throughput; but the defining characteristic of a TRNG is nondeterminism from physical entropy.
Therefore, option B is correct.
NEW QUESTION # 65
(What is an alternative to using a Certificate Revocation List (CRL) with certificates?)
Answer: C
Explanation:
OCSP is the primary online alternative to CRLs for checking whether a certificate has been revoked. With a CRL, a relying party periodically downloads a list of revoked certificate serial numbers published by the issuing CA (or CRL distribution point). That approach can be bandwidth-heavy, introduces latency between revocation and client awareness, and can result in clients using stale revocation data if updates are infrequent.
OCSP improves this by allowing a client (or a server on the client's behalf) to query an OCSP responder in near real time about the status of a specific certificate (good, revoked, or unknown). In practice, many TLS deployments use OCSP stapling, where the server periodically fetches a signed OCSP response from the CA's responder and "staples" it to the TLS handshake, reducing client-side network calls and improving privacy (the CA doesn't learn which site the client is visiting). Thus, OCSP provides a more timely, certificate- specific revocation status mechanism than CRLs while preserving the CA's signed assurance.
NEW QUESTION # 66
(What is an example of a block cipher mode of operation?)
Answer: C
Explanation:
A block cipher mode of operation defines how a block cipher (such as AES) is applied to data longer than a single block, and how blocks are linked (or not linked) to provide certain security properties. ECB (Electronic Codebook) is one of the canonical block cipher modes: it encrypts each plaintext block independently using the same key. While ECB is generally discouraged because it leaks patterns (identical plaintext blocks produce identical ciphertext blocks), it is still a valid and historically important mode of operation and is often used as a teaching example of what not to do for structured data. In contrast, SHA-256 is a hash function (one- way digest) and not a mode for block ciphers. DSA is a digital signature algorithm and provides authenticity
/integrity, not encryption mode behavior. RSA is an asymmetric cryptosystem, not a block cipher mode.
Therefore, among the options, ECB is the correct example of a block cipher mode of operation.
NEW QUESTION # 67
(An organization wants to digitally sign its software to guarantee the integrity of its source code. Which key should the customer use to decrypt the digest of the source code?)
Answer: D
Explanation:
When software is digitally signed, the organization computes a cryptographic hash (digest) of the software (or its manifest) and then signs that digest using the organization's private key. Verification works in the opposite direction: the customer (verifier) uses the organization's public key to validate the signature and recover/confirm the signed digest, then independently hashes the received software and compares the result. If the digests match and the signature validates under the public key, the customer has strong assurance that the software has not been altered since it was signed and that it was signed by the holder of the corresponding private key. The customer never needs the organization's private key-sharing it would destroy security and enable forgery. Likewise, the customer's own keys are irrelevant to verifying the publisher's signature. The organization's public key is typically delivered inside a certificate chain (code signing certificate) so the verifier can also validate publisher identity and trust. Therefore, the customer uses the organization's public key for signature verification (often described as "decrypting" the signed digest).
NEW QUESTION # 68
(What is the length (in bits) of a SHA-1 hash output?)
Answer: C
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
