WebbIf the ciphertext is decrypted with the same secret DES key "0E329232EA6D0D73", the result is the original plaintext "8787878787878787". This example is neat and orderly because our plaintext was exactly 64 bits long. The same would be true if the plaintext happened to be a multiple of 64 bits. But most ... Webba given ciphertext with the same probability, i.e., given any pair of M 0 and M 1, the probabilities that they are encrypted into a ciphertext C are the same – Hence no adversary can tell whether C is ciphertext of M 0 or M 1. • IND-CPA means – With bounded computational resources, the adversary cannot tell which of M 0 and M 1 is ...
