Overview
EP2: Assume a block cipher achieving the avalanche effect is used. Does this guarantee that the encryption algorithm has the same effect?
Explain your answer (if yes, prove it; if no, give a counter example).
The avalanche effect is a property of any encryption algorithm such that a small change in either the plaintext or the key produces a significant change in the ciphertext.
No, the encryption algorithm doesn’t have the same effect,
We will take random key and random plain text and encrypt using CTR then flip one bit and encrypted again to find out how many bits are effected in the ciphertext
