NEW QUESTION # 35
(How does a Caesar cipher operate in the encryption of messages?)
Answer: D
Explanation:
A Caesar cipher is a classic monoalphabetic substitution cipher where each plaintext letter is replaced by a letter a fixed number of positions away in the alphabet. For example, with a shift of 3, A becomes D, B becomes E, and so on, wrapping around at the end (X#A, Y#B, Z#C). This "fixed shift" is the entire key: both sender and receiver must know the shift value to encrypt and decrypt. Decryption simply shifts letters back by the same amount. The Caesar cipher illustrates foundational cryptographic ideas: key-based transformation, reversible mapping, and the importance of key space size. Because the key space is tiny (only 25 meaningful shifts in the Latin alphabet), it is easily broken by brute force. It is also vulnerable to frequency analysis because letter frequency patterns in the ciphertext resemble those of the plaintext, just relabeled. While historically important for introducing substitution concepts, it provides no meaningful security by modern standards. The defining operation is the fixed positional shift, which directly matches option D.
NEW QUESTION # 36
(A security analyst is using 3DES for data encryption. Which 3DES key size is valid?)
Answer: A
Explanation:
3DES (Triple DES) applies the DES block cipher three times to increase effective security, and its commonly cited valid key sizes correspond to how many independent DES keys are used. Two-key 3DES uses two 56- bit DES keys (K1 and K2) in an EDE sequence (Encrypt with K1, Decrypt with K2, Encrypt with K1), yielding 112 bits of keying material (ignoring parity bits). Three-key 3DES uses three independent 56-bit keys for a total of 168 bits of keying material, but that option is not listed here. A 56-bit key corresponds to single DES, not 3DES. 128-bit is associated with AES, not 3DES. 2,048-bit is typical for RSA keys, not symmetric ciphers. Therefore, among the choices provided, 112-bit is a valid 3DES key size. While 3DES is now deprecated for many uses due to its 64-bit block size and performance limitations, understanding its keying options remains important for legacy system assessment.
NEW QUESTION # 37
(What are the roles of keys when using digital signatures?)
Answer: B
Explanation:
Digital signatures provide integrity, authenticity, and typically non-repudiation by using an asymmetric key pair. The signer uses the private key to create a signature over a message (usually over a hash
/digest of the message). Because the private key is kept secret, only the legitimate signer should be able to produce a valid signature. Anyone who has the corresponding public key can then validate the signature: they verify that the signature matches the message digest under the public key and that the signed data has not been altered. This is why the public key can be widely distributed (often inside an X.
509 certificate) while the private key must be protected by the signer. If a public key were used to sign, anyone could forge signatures; if a private key were required for validation, only the signer could validate, defeating the purpose of public verifiability. Therefore, the correct key roles are private key for signing and public key for signature validation.
NEW QUESTION # 38
(How does Electronic Codebook (ECB) mode encryption function?)
Answer: D
Explanation:
ECB is the simplest block cipher mode: each plaintext block is encrypted independently using the same key and the block cipher primitive. There is no IV and no chaining, so identical plaintext blocks produce identical ciphertext blocks. This property leaks patterns and structure in the plaintext, which is why ECB is generally considered insecure for most real-world data beyond tiny, random-looking inputs. For example, images encrypted with ECB often reveal outlines because repeated pixel blocks map to repeated ciphertext blocks.
Option A describes CTR mode, option C describes CBC mode, and option B resembles feedback-based modes. ECB's independence also means it can be parallelized, but the pattern leakage is a severe weakness.
Modern practice prefers authenticated encryption modes (like GCM) or, at minimum, modes with IVs and chaining (like CBC with proper padding and MAC). Therefore, the correct statement is that ECB encrypts each block with the same key and each block is independent of the others.
