  • Niederreiter cryptosystem — In cryptography, the Niederreiter cryptosystem is a variation of the McEliece Cryptosystem developed in 1986 by Harald Niederreiter [1]. It applies the same idea to the parity check matrix H of a linear code. Niederreiter is equivalent to… …   Wikipedia

  • Merkle–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… …   Wikipedia

  • Unicity distance — is a term used in cryptography referring to the length of an original ciphertext needed to break the cipher by reducing the number of possible spurious keys to zero in a brute force attack. That is, after trying every possible key, there should… …   Wikipedia

  • Linear cryptanalysis — In cryptography, linear cryptanalysis is a general form of cryptanalysis based on finding affine approximations to the action of a cipher. Attacks have been developed for block ciphers and stream ciphers. Linear cryptanalysis is one of the two… …   Wikipedia

  • Disk encryption theory — Disk encryption is a special case of data at rest protection when the storage media is a sector addressable device (e.g., a hard disk). This article presents cryptographic aspects of the problem. For discussion of different software packages and… …   Wikipedia
