摘要
本文利用Σ^n上单向置换与完善置换的复合,构造基于强单向转换的杂凑算法,并证明了该算法的安全性等价于单向置换在多项式时间内不可求逆。
This paper constructs the Hash algorithm based on strong one-way permutation by the composition of one-way permutation and perfect permutation on ∑n and proves that its security is equivalent to the one-way permutation that can not be inversed in polynomial time.
