NEW QUESTION # 71
(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 # 72
(Why are large prime numbers important in cryptography?)
Answer: C
Explanation:
Large prime numbers are crucial because they enable cryptosystems where certain operations are easy to perform, but reversing them is computationally hard without secret information. In RSA, security is based on the difficulty of factoring a large composite number that is the product of two large primes; multiplying primes is easy, but factoring the product is believed to be hard at sufficient sizes. In Diffie-Hellman and related systems, primes define finite groups (often modulo a large prime) where exponentiation is efficient but the discrete logarithm problem is hard. Primes also help ensure desirable group properties-such as having a large cyclic subgroup-reducing vulnerabilities from small subgroups or weak structure. The value of "large" is that it makes brute-force and known algorithmic attacks infeasible with current computing resources. Large primes do not primarily make encryption faster, nor do they make decryption easier; they are chosen to maximize security margins. While primes can be involved in encoding steps, their importance is security: they form the mathematical foundation for hardness assumptions used by major public-key algorithms. Therefore, the best answer is that they provide security in encryption algorithms.
NEW QUESTION # 73
(How are limits managed for the number of bitcoins that can be created and stored in a blockchain?)
Answer: B
Explanation:
Bitcoin's supply is controlled by protocol rules enforced by consensus: new bitcoins enter circulation through the block subsidy awarded to miners for producing valid blocks. This subsidy is programmed to halve at fixed intervals (every 210,000 blocks), which steadily reduces the rate of new coin creation over time and asymptotically approaches a capped total supply (commonly cited as 21 million BTC). This mechanism is often called the halving schedule and is the primary way limits are managed. The number of participants is not fixed; anyone can run a node or mine. There is no per-country cap and no per-person maximum enforced by the protocol-addresses and ownership are not limited that way. The supply cap emerges from the decreasing issuance schedule combined with consensus validation rules that reject blocks creating coins beyond what the schedule allows. Therefore, the correct answer is that limits are managed because rewards for mining reduce over time.
NEW QUESTION # 74
(How often are transactions added to a blockchain?)
Answer: C
Explanation:
For Bitcoin, transactions are confirmed by inclusion in blocks, and the network targets an average block interval of about 10 minutes. That means transactions are "added" to the Bitcoin blockchain approximately every 10 minutes in the sense that a new block containing a batch of transactions is appended at that cadence.
The 10-minute target is achieved by a difficulty adjustment mechanism that recalibrates mining difficulty roughly every 2016 blocks, aiming to keep the average interval stable despite changes in total network hash power. It is important to note that this is an average: blocks can be found faster or slower in the short term due to the probabilistic nature of proof-of-work mining. Other blockchains have different block times (seconds to minutes), but the question's options and typical curriculum context align with Bitcoin's 10-minute design.
Therefore, the correct choice is approximately every 10 minutes.
NEW QUESTION # 75
(Which certificate encoding process is binary-based?)
Answer: B
Explanation:
DER (Distinguished Encoding Rules) is a binary encoding format used to represent ASN.1 structures in a canonical, unambiguous way. X.509 certificates are defined using ASN.1, and DER provides a strict subset of BER (Basic Encoding Rules) that guarantees a single, unique encoding for any given data structure. That
"unique encoding" property is important for cryptographic operations such as hashing and digital signatures, because different encodings of the same abstract data could otherwise produce different hashes and break signature verification. In contrast, PEM is not a binary encoding; it is essentially a Base64-encoded text wrapper around DER data, bounded by header/footer lines (e.g., "BEGIN CERTIFICATE"). PKI is an overall framework for certificate issuance, trust, and lifecycle management-not an encoding. RSA is an asymmetric algorithm used for encryption/signing, not a certificate encoding format. Therefore, the binary-based certificate encoding process among the options is DER.
