51Wall box — Wall boxes are a type of post box or letter box found in many countries including France, the United Kingdom, the Commonwealth of Nations, Crown dependencies and Ireland. They differ from pillar boxes in that, instead of being a free standing… …
52MDC-2 — In cryptography, MDC 2 (Modification Detection Code 2, sometimes called Meyer Schilling) is a cryptographic hash function. MDC 2 is a hash function based on a block cipher with a proof of security in the ideal cipher model[1]. The length of the… …
53Brute force attack — In cryptanalysis, a brute force attack is a method of defeating a cryptographic scheme by trying a large number of possibilities; for example, possible keys in order to decrypt a message. In most schemes, the theoretical possibility of a brute… …

56Merkle–Hellman knapsack cryptosystem — The Merkle–Hellman knapsack cryptosystem was one of the earliest public key cryptosystems invented by Ralph Merkle and Martin Hellman in 1978.[1] Although its ideas are elegant, and far simpler than RSA, it has been broken.[2] Contents 1… …
57Key (cryptography) — In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a key, the algorithm would produce no useful result. In encryption, a key specifies the… …
58Code (cryptography) — For other uses, see Code (disambiguation). In cryptography, a code is a method used to transform a message into an obscured form, preventing those who do not possess special information, or key, required to apply the transform from understanding… …
