基于布尔置换的ElGamal体制

ElGamal Cryptosystem Based on Boolean Permutation

在现有的公钥密码系统中,大部分算法有信息膨胀的缺点。文章根据布尔置换的特点对ElGamal体制进行了改进,使信息的膨胀率降低,并且新体制可以避免一些原有的攻击。

In existing public key cryptosystems,most of them have drawbacks of information expansion.In this paper we improve on ElGamal Cryptosystem based on the characteristic of Boolean permutation,it can decrease the rate of information expansion and avoid some previous attacks.
