公钥密码系统以其算法设计简单、安全性高已经成为密码学领域的一个非常重要的研究课题。为了更加高效地构造公钥密码系统，文中利用方程Ax＋By=C的解的不定性，提出了将两个加密算法复合成新加密算法的方法，对此做了分析，并给出了具体例子。实践表明，这种基于复合加密的公钥密码系统，算法的时间复杂度和空间复杂度并未受到影响。但其安全性较早期各同类系统更高、更易被用户采纳

Public key eryptosystem has become a very important research topic in cryptography field for its simple algorithm design and high security. To build public key cryptosystem more effectively,gave a method to make a new cryptosystem from two given cryptosystems using the Diophantine equation Ax ＋ By = C,then analyzed the method and gave some examples. It is proved that this public key cryptosystern based on compound encryption has not been influenced on time complexity and space complexity, but it has more security than the early systems and is much easier to he adopted by users
