摘要
RSA加密算法是第一个较为完善的公开密钥算法,混沌密码算法是一种快速加密算法,在安全性要求较高的领域中,有着非常广阔的应用前景．在分析了RSA公钥加密系统和混沌加密各自的优点及其存在的安全问题的基础上,提出了一种新的分组双密密钥密码方案．这种密码方案是一种并联的混合密码系统．理论分析表明,这种方案要比单独使用其中任何一种加密方案保密性能好,代价低．
RSA is the first comparatively perfect Public Key Algorithm. As a fast encryption algorithm, the chaotic cryptographic method has quite wide applications in the field of security. In this paper, through analyzing the advantages and security of RSA eneryption system and chaotic encrypt, a new grouping double-key cryptogram scheme is presented. It is a shunt-wound hybrid crypto-systcm. The results of theoretic analysis show that the secrecy capability and cost of the proposed scheme are better than those of any scheme mentioned in the preamble.
