中文摘要： 基于公钥密码体制数字证书可以为协议双方提供安全性较高的身份认证，为短期通信伙伴提供快速、安全、可靠的密钥交换算法成为信息安全领域中研究热点之一。传统密钥交换算法在短期通信领域中受到身份认证、阻塞性拒绝服务攻击和假冒攻击的限制。本项目延伸了多态性密码理论的内涵，采用自编译器扩展因子方法，采集密钥协商双方各自持有含本身信息的随机参数组PARASa和PARASb；通信双方共同构造出可证明高度非线性的新型SPN核心算法，生成更加安全、高效的多态性虚S-盒，以对称性密码机制完成公钥密码学特性的秘密分割方法；从钥控可变的角度研究基于对称性密码理论的短期通信伙伴密钥交换协议,多态性密钥交换协议核心算法在密码学特性上以期达到满足严格雪崩准则、高度非线性和输出位独立性三个准则，可以抵抗未知密钥共享和密钥泄露伪装攻击。本项目的研究成果将为解决短期通信伙伴基于对称性密码体制的密钥交换难题提供理论上的依据。

英文摘要： Many efficient identity authenticated key agreement protocols are provied by digital certificate based on public key cryptography.It has become one of research hotspots in the field of information security to provide fast, secure and reliable key exchange algorithms for the short-term communications partner. Traditional key exchange algorithm in the field of short-term communications subject to the limit of authentication, the obstructive denial of service attacks and disguised attacks. This project extends the connotation of polymorphic cipher theory,makes use of the method of self-compiler based expansion factor to collect random parameter sets hold by each of the parties containing its own information PARASa and PARASb. Both parties jointly construct a new highly nonlinear SPN core algorithm. The more efficient polymorphism virtual S-boxes is constructed. The method of secret split for the public key cryptography features can be implemented by symmetry cipher system. The polymorphic key exchange protocol core algorithms constructed to meet the strict avalanche criterion, highly nonlinear and the bit independence criterion of the three criteria in cryptography features.The algorithm is immune to unknown key-share attack and leak key disguised attack.The research results of this project will provide a theoreti
