Question

Quizplus · Accepted Answer

Stream ciphers operate on plaintext one bit at a time.

Answer: E 
 Hashing produces a fixed-size output (message digest) from any size of input data.

Answer: I 
 Block ciphers operate on fixed-size blocks of plaintext at a time.

Answer: D 
 Certificates are digital documents used in public key infrastructure that bind a public key to a certain entity (individual, organization, etc.).

Answer: F 
 A collision occurs when two different inputs produce the same output in a hashing function.

Note: Asymmetric encryption (A) involves two different keys for encryption and decryption, while symmetric encryption (C) uses the same key for both. Therefore, neither A nor C operate on plaintext one bit at a time. Collision-free (B) is a property of hashing functions, not a specific method.
