Hash functions are often used in the authentication of information security field. With the development of electronic commerce, the reliability of authentication is paid more and more attention to. This paper describes an N - LFSR which combined nonlinear S - box with the LF-SR, and substitutes it for CLS operator in hash function. The efficiency of new hash function is not drop and the ability of defence attack is strengthened.
