本文基于E1Gamal体制,以迭代加密的思想,利用构造安全有效的概率公开钥密码体制的一般方法,建立了一种新的概率加密公钥体制。
Based on ElGamal, a new Probabilistic Encryption Cryptosystem(PEC) is given in this paper. The new PEC based on iterative encryption is proposed according to a general algorithmic scheme for constructing secure and efficient probabilistic public-key cryptosystem.
