| 摘 要： | 现有的公开钥密码的安全性标准主要有三个;多项式安全、语义安全、A.C.Yao 安全.这些安全性标准实质上都是等价的.而且仅适宜于概率型公开钥密码.本文给出一种新的安全性标准:统计安全性及其等价形式,新标准能用来测定任何公开钥密码的安全强度,以满足不同用户的需要.

| Abstract: | Three security criteria of public key cryptosystem have been proposed:polynormal security, semantic security,A.C.Yao security.All of them are equivalent and used in probabilistic key cryptosystems.In this paper,a new security.statistic security and its equivalent form,is given. The new security can be used in any public key cryptosystem to satisfy the needs of the different custom. |
