  • Key server (cryptographic) — In computer security, a key server is a computer mdash; typically running special software mdash; which provides cryptographic keys to users or other programs. The users programs can be working on the same network as the key server or on another… …   Wikipedia

  • Hybrid cryptosystem — In cryptography, public key cryptosystems are convenient in that they do not require the sender and receiver to share a common secret in order to communicate securely (among other useful properties). However, they often rely on complicated… …   Wikipedia

  • Key escrow — (also known as a fair cryptosystem) is an arrangement in which the keys needed to decrypt encrypted data are held in escrow so that, under certain circumstances, an authorized third party may gain access to those keys. These third parties may… …   Wikipedia

  • Public-key cryptography — In an asymmetric key encryption scheme, anyone can encrypt messages using the public key, but only the holder of the paired private key can decrypt. Security depends on the secrecy of that private key …   Wikipedia

  • McEliece cryptosystem — In cryptography, the McEliece cryptosystem is an asymmetric encryption algorithm developed in 1978 by Robert McEliece.[1] It was the first such scheme to use randomization in the encryption process. The algorithm has never gained much acceptance… …   Wikipedia

  • Rabin cryptosystem — The Rabin cryptosystem is an asymmetric cryptographic technique, whose security, like that of RSA, is related to the difficulty of factorization. However the Rabin cryptosystem has the advantage that the problem on which it relies has been proved …   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

  • Paillier cryptosystem — The Paillier cryptosystem, named after and invented by Pascal Paillier in 1999, is a probabilistic asymmetric algorithm for public key cryptography. The problem of computing n th residue classes is believed to be computationally difficult. This… …   Wikipedia

  • Naccache–Stern knapsack cryptosystem — Note: this is not to be confused with the Naccache–Stern cryptosystem based on the higher residuosity problem. The Naccache–Stern Knapsack Cryptosystem is an atypical public key cryptosystem developed by David Naccache and Jacques Stern in 1997.… …   Wikipedia

  • Goldwasser-Micali cryptosystem — The Goldwasser Micali cryptosystem (GM) is an asymmetric key encryption algorithm developed by Shafi Goldwasser and Silvio Micali in 1982. GM has the distinction of being the first probabilistic public key encryption scheme which is provably… …   Wikipedia

  • Symmetric-key algorithm — Symmetric key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.The encryption key is trivially related to the decryption key, in that they may …   Wikipedia
