Known Ciphertext attack is an attack on cryptography as well.
“known ciphertext attack is an attack model for cryptanalysis where the attacker is assumed to have access only to a set of ciphertexts.
The attack is completely successful if the corresponding plaintexts can be deduced, or even better, the key. The ability to obtain any information at all about the underlying plaintext is still considered a success. For example, if an adversary is sending ciphertext continuously to maintain traffic-flow security, it would be very useful to be able to distinguish real messages from nulls. Even making an informed guess of the existence of real messages would facilitate traffic analysis.”
I choose BCE
Man-in-the-Middle attack cannot be Crypto-analysis attack, therefore the answer should BDE.
in my opinion the correct answer is A B D. Because in case of replay attack just replaying the datas.
