Short Content: IntroductionIn the information field, the crypto-algorithm uses in protecting the information the secrecy, the integrity and the security, puts briefly is prevents the information fabrication and steals. The crypto-algorithm may divide into the symmetrical crypto-algorithm and the asymmetrical crypto-algorithm. The symmetrical crypto-algorithm's characteristic is the speed quick, the working strength is high, mainly serves as the data encryption algorithm. The symmetrical crypto-algorithm may divide into the block cipher algorithm and the sequential cipher algorithm according to the encryption pattern. The ...
