【Abstract】 Cryptosystem is the kernel technology of computer security, symmetric\|key cryptosystems has high speed of encrpytion and decryption, but it can not achieve the vast key management, and public\|key cryptosystems solve the problem of key management, but it is low inspeed. In this paper, a unitary mathematical frame of cryptosystems is presented based on the symmetric\|key and public\|key cryptosystems, from which the two fast and efficient public\|key algorithms are constructed, which, while maintaining their previous advantages, are highly efficient.更多还原
