Question

Quizplus · Accepted Answer

Block cipher operates on blocks of plaintext.

Answer: A
 Asymmetric encryption refers to the use of two keys, a public key and a private key, in encryption and decryption respectively.

Answer: E
 Hashing refers to transforming data of arbitrary size into a fixed-size output known as a hash.

Answer: H
 Message digest refers to a fixed-size output obtained through the use of a hashing algorithm.

Answer: G
 Stream cipher operates on individual bits or bytes of plaintext, as opposed to operating on blocks of plaintext.

The other statements are incorrect:

B) Collision-free refers to the absence of two inputs producing the same output in a hashing algorithm.

C) Symmetric encryption uses the same key for encryption and decryption.

D) Certificate refers to a digitally signed document associating an entity with a public key or other attributes.

F) Collision refers to the situation where two different inputs produce the same output in a hashing algorithm.
