Question

Different encryption keys generate the same ciphertext from the same plaintext message.

A) Key Equivalence
B) Key Duplication
C) Key Clustering
D) Key Divergence

Answer 1

Key Clustering is the term used when different encryption keys produce the same ciphertext from the same plaintext, potentially reducing cryptographic strength.

Step-by-step explanation:

When different encryption keys generate the same ciphertext from the same plaintext message this phenomenon is known as Key Clustering. Key clustering is an aspect of cryptographic systems where two different keys produce identical output (ciphertext) for the same input (plaintext).

This situation can be a potential concern in cryptographic systems because it may reduce the effective strength of the encryption by introducing the possibility that multiple keys could decrypt a message thus potentially allowing unintended parties to access the information.
