Yuan Guo · Zhongyang Minzu Daxue xuebao · 2009
Based on the RSA public key cryptosystem,a probabilistic public key cryptosystem is presented in this paper,using the techniques of time stamp and hash function.In this scheme encoding and decoding have the same operation compared with the RSA,but it is secure for polynomial.At the same time,the problem of great message expansion in probabilistic cryptosystem is solved,the message expansion in this paper is 1.
