A.
Key collision

B.
Key clustering

C.
Hashing

D.
Ciphertext collision

Explanation:
In cryptography, key clustering is said to occur when two different keys generate the same ciphertext from the
same plaintext, using the same cipher algorithm. A good cipher algorithm, using different keys on the same
plaintext, should generate a different ciphertext, irrespective of the key length.Incorrect Answers:
A: Key collision is not the correct term to describe an instance of two different keys generating the same
ciphertext from the same plaintext.
C: Hashing is the transformation of a string of characters into a usually shorter fixed-length value or key that
represents the original string. This is not what is described in the question.
D: Ciphertext collision is not the correct term to describe an instance of two different keys generating the same
ciphertext from the same plaintext.
