EFF DES cracker

Index EFF DES cracker

In cryptography, the EFF DES cracker (nicknamed "Deep Crack") is a machine built by the Electronic Frontier Foundation (EFF) in 1998, to perform a brute force search of the Data Encryption Standard (DES) cipher's key space – that is, to decrypt an encrypted message by trying every possible key.

Block cipher

In cryptography, a block cipher is a deterministic algorithm operating on fixed-length groups of bits, called a block, with an unvarying transformation that is specified by a symmetric key.

Cryptanalysis

Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to loosen" or "to untie") is the study of analyzing information systems in order to study the hidden aspects of the systems.

Cryptanalytic computer

A cryptanalytic computer is a computer designed to be used for cryptanalysis, which nowadays involves massive statistical analysis and multiple trial decryptions that since before World War II are possible only with automated equipment.

Crypto Wars

The Crypto Wars is an unofficial name for the U.S. and allied governments' attempts to limit the public's and foreign nations' access to cryptography strong enough to resist decryption by national intelligence agencies (especially USA's NSA).
