Question

Quizplus · Accepted Answer

Symmetric encryption uses a single key to encrypt and decrypt data.

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

Answer: I
 A block cipher encrypts data in fixed-size blocks.

Answer: E
 Hashing is a process of converting data into a fixed-size output, also known as a message digest.

Answer: G
 A stream cipher encrypts data one bit or byte at a time, as opposed to block ciphers that encrypt fixed-size blocks.

The other terms include:
A) Asymmetric encryption uses a pair of keys: a public key and a private key for encryption and decryption, respectively.
B) Collision free means that it is highly improbable for two different inputs to produce the same output in a hashing function.
D) A certificate is a digital document that verifies the identity of a particular entity or individual.
H) A message digest is the output of a hashing function, which serves as a unique identifier for the input data.
