基于Chebyshev的概率公钥密码体制
Probabilistic public-key cryptosystem based on Chebyshev
摘要
Abstract
This paper introduced the definition and the properties of Chebyshev polynomial.According to the deterministic public-key cryptosystem of Chebyshev polynomial,found that it couldn't resist chosen cipher-text attacks.Combining with the security model against chosen cipher-text attacks,this paper proposed the probabilistic public-key cryptosystem of Chebyshev polynomial.The analysis show that the proposed cryptosystem is correct.Through the result of the reduction proof,the proposed cryptosystem can resist the adaptive chosen cipher-text attacks and has the IND-CCA2 security.关键词
