33. Frage
(Which authentication method allows a web service installed on a network operating system to prove its identity to a customer?)
Antwort: B
Begründung:
One-way server authentication is the standard model used by most TLS-enabled web services to prove the server's identity to a client. In this model, the server presents an X.509 certificate during the TLS handshake. The client validates the certificate chain to a trusted root CA, checks hostname binding (CN
/SAN), validates validity dates, and may check revocation status. If validation succeeds, the client gains cryptographic assurance that it is communicating with the holder of the private key corresponding to the server certificate's public key, and that the certificate is issued to the expected domain/identity. This proves the server's identity to the customer without requiring the customer to present a certificate.
Mutual authentication would require both client and server to authenticate each other using certificates (commonly in certain enterprise APIs), but the question asks specifically about the web service proving its identity to the customer, which is satisfied by server-only authentication. One-way client authentication is the opposite direction (client proves identity to server). "End-to-end authentication" is a broader concept and not the specific TLS identity proof mechanism described here. Thus, one-way server authentication is the correct choice.
34. Frage
(What describes a true random number generator?)
Antwort: C
Begründung:
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.
35. Frage
(Which cryptographic operation has the fastest decryption process?)
Antwort: C
Begründung:
Symmetric cryptography generally provides the fastest encryption and decryption performance among common cryptographic operations. Algorithms like AES and ChaCha20 are designed for high throughput and efficient implementation in software and hardware (e.g., AES-NI acceleration). Symmetric decryption is computationally similar in cost to symmetric encryption, and both are far faster than asymmetric operations for equivalent security levels. Asymmetric cryptography (RSA, ECC) involves expensive mathematical operations (modular exponentiation or elliptic-curve scalar multiplication), making it much slower and unsuitable for bulk data decryption. That is why real-world secure protocols use asymmetric cryptography primarily to authenticate peers and establish keys, then switch to symmetric encryption for the actual data stream. Hashing is not decryption at all; it is one-way, and there is no "decrypt" operation for a hash. Padding is not a decryption mechanism; it is a formatting step used with block ciphers to align plaintext length.
Therefore, the correct choice for the operation with the fastest decryption process is symmetric cryptography.
36. Frage
(What is the value of 23 mod 6?)
Antwort: C
Begründung:
The expression 23 mod 6 asks for the remainder when 23 is divided by 6. Modular arithmetic is foundational in cryptography, especially in public-key systems (RSA, Diffie-Hellman, ECC) where operations occur in finite rings or fields. To compute 23 mod 6, identify the largest multiple of 6 that does not exceed 23. Multiples of 6 are 6, 12, 18, 24. Since 24 is greater than 23, the largest valid multiple is 18. Subtract: 23 # 18 = 5, so the remainder is 5. Therefore, 23 mod 6 = 5, which corresponds to option
"05." Modular reduction keeps numbers within a fixed range (0 to modulus#1), enabling stable arithmetic under wraparound behavior. In cryptographic protocols, this wraparound property is essential for defining groups and ensuring operations remain bounded and consistent.
37. Frage
(What is a characteristic of a hash function?)
Antwort: C
Begründung:
A cryptographic hash function maps input data of arbitrary length to a fixed-length digest and is designed to be one-way: given a digest, it should be computationally infeasible to recover the original input (preimage resistance). This one-way property enables many security applications: file integrity checking (any change alters the digest), password storage (combined with salt and slow hashing), digital signatures (signing a digest rather than large data), and commitment schemes. Hash functions are not encryption because they do not support decryption; they intentionally discard information about the input. They also do not use public/private key pairs; those are features of asymmetric cryptography. "Reversible" is the opposite of the intended design goal. A well-designed hash also aims for collision resistance (hard to find two different inputs with the same digest) and second-preimage resistance. Among the answer choices, the defining characteristic that best captures what makes a hash function distinct is that it is one-way.
