Akey generator[1][2][3] is a protocol or algorithm that is used in manycryptographicprotocols to generate a sequence with manypseudo-random characteristics. This sequence is used as anencryption key at one end of communication, and as a decryption key at the other. One can implement a key generator in a system that aims to generate, distribute, and authenticate[4] keys in a way that without the private key, one cannot access the information in the public end.[5]
Examples of key generators includelinear-feedback shift registers (LFSR) and theSolitaire (or Pontifex) cipher.
