| Abstract: |
| One—way hash functions is an important part of cryptography.In this pa-per,a new method for constructing one—way hash function F from any fixed size one—way hash function f：∑m→∑t,m>t，is presented，the property of which is that it is easy to
be parallelized． |
| Key words: Fixed size one—way hash function,one—way hash function,collision． |
