Which of the following is true about encryption algorithms?
A) their strength is tied to their key length
B) not vulnerable to brute force attacks
C) block ciphers encrypt one bit at a time
D) asymmetric algorithms use a single key

Question

Quizplus · Accepted Answer

The strength of an encryption algorithm is directly tied to the length of its key. Longer keys are exponentially more difficult to crack than shorter ones.

Answer: B
 No encryption algorithm is completely immune to brute force attacks, but some are more vulnerable than others. A good encryption algorithm should have a high degree of resistance to such attacks.

Answer: False
 Block ciphers encrypt blocks of data at a time, typically ranging from 64 to 256 bits per block. They do not encrypt one bit at a time.

Answer: D
 Asymmetric encryption algorithms use a pair of keys, a public key that is used to encrypt data and a private key that is used to decrypt it. They do not use a single key.
