Combined one byte at a time with the plaintext stream using the XOR operation, a __________ is the output of the pseudorandom bit generator.
A) keystream
B) digital signature
C) secure hash
D) message authentication code

Question

Quizplus · Accepted Answer

A keystream is the output of a pseudorandom bit generator when combined one byte at a time with the plaintext stream using the XOR operation. Digital signatures, secure hashes, and message authentication codes are different concepts related to cryptography but not directly related to the output of a pseudorandom bit generator.
