A desirable property of an encryption algorithm is that small changes in key valuesproduces small changes in the output ciphertexta.Falseb.True

Answer

The statement that "a desirable property of an encryption algorithm is that small changes in key values produce small changes in the output ciphertext" is False.

Explanation

In encryption algorithms, a property known as the "avalanche effect" is often desired. This means that a small change in either the plaintext (the data being encrypted) or the key should produce a significant (ideally, unpredictable) change in the ciphertext (the encrypted output).

Thus, small changes in key values should lead to large changes in the output ciphertext, making it difficult for an attacker to derive the key or plaintext from the ciphertext. So, the correct answer is:

a. False
