Cryptanalysis Definition & Meaning - Merriam-Webster

WebThe attack involves working from either end of the encryption chain toward the middle, as opposed to trying brute-force permutations from one end of the encryption process to the other. Essentially, meet-in-the-middle attacks involve breaking the encryption process into simpler, separate steps instead of one long, complex chain.
