NEW QUESTION # 20
(What type of encryption uses different keys to encrypt and decrypt the message?)
Answer: C
Explanation:
Asymmetric encryption (also called public key cryptography) uses a pair of mathematically related keys: a public key and a private key. One key is used to encrypt, and the other is used to decrypt, which is the defining "different keys" property asked in the question. In the common confidentiality use case, a sender encrypts a message using the recipient's public key, and only the recipient can decrypt it using their private key. This solves the key distribution problem inherent in symmetric encryption, where both parties must securely share the same secret key in advance. Asymmetric systems also enable digital signatures: the private key signs (creates a signature) and the public key verifies it, providing authenticity and integrity. Symmetric encryption, by contrast, uses the same shared key for both encryption and decryption (even though internal round keys may exist, it is still one shared secret). "Private key" alone is not a full encryption type, and
"secure" is a generic description rather than a cryptographic category. Therefore, the correct answer is D.
Asymmetric.
NEW QUESTION # 21
(What is the value of 51 mod 11?)
Answer: C
Explanation:
The value 51 mod 11 is the remainder after dividing 51 by 11. Modular arithmetic is widely used in cryptography to keep computations within a finite set of residues, such as in RSA where values are taken modulo n, or in Diffie-Hellman where exponents and group elements are reduced modulo a prime. To compute 51 mod 11, find the largest multiple of 11 less than or equal to 51. Multiples of 11 are 11, 22, 33, 44,
55. The closest without exceeding 51 is 44. Subtracting gives 51 # 44 = 7, so the remainder is 7. Therefore, 51 mod 11 = 7, matching option "07." This remainder is always in the range 0 through 10 because the modulus is
11. Such residue computations underpin the "wraparound" behavior that makes modular exponentiation and inverse computations well-defined in cryptographic groups.
NEW QUESTION # 22
(Which certificate encoding process is binary-based?)
Answer: C
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.
NEW QUESTION # 23
(A security analyst uses a polyalphabetic substitution cipher with a keyword of YELLOW to encrypt a message. Which cipher should be used to encrypt the message?)
Answer: A
Explanation:
A polyalphabetic substitution cipher uses multiple substitution alphabets rather than a single fixed mapping.
The classic cipher that uses a keyword to select shifting alphabets across the message is the Vigenere cipher.
In Vigenere, each plaintext letter is shifted by an amount determined by the corresponding key letter (repeating the keyword as needed). For example, a keyword like "YELLOW" is aligned under the plaintext; each key character defines a Caesar shift (A=0, B=1, ...) applied to the plaintext character, producing ciphertext. This rotation of alphabets across positions makes Vigenere more resistant to simple frequency analysis than monoalphabetic substitution, because the same plaintext letter may encrypt to different ciphertext letters depending on its position relative to the key. The Pigpen cipher is a symbol substitution cipher, Caesar is monoalphabetic with a single shift, and Playfair is a digraph substitution cipher using a 5×5 key square, not the repeating-key polyalphabetic method described. Therefore, the correct cipher is Vigenere.
NEW QUESTION # 24
(Why are large prime numbers important in cryptography?)
Answer: D
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.
