Homework Help: Meet in the middle attack on 2DES

  1. Nov 16, 2012 #1
    What is the probability that the meet in the middle attack on 2DES where the attacker knows three plaintexts and corresponding pairs of ciphertexts will succeed?

    I get how the meet in the middle attack works when the adversary just knows 1 plaintext and ciphertext, but I do not understand what to do when there's more than one. Any constructive help would be great. Thanks!
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
