这篇论文考察关键管理的基本内容,指出存在关键协议协议的限制。它详细介绍 RSA 公钥 cryptosys-tems 并且在整数戒指的同构的加密计划。同形钥匙协议基于 RSA 被介绍。与 Diffie-Hellman 协议相比,它的操作速度快速是更多;与关键协议协议相比基于口令,它有更好的安全。协议能使用 RSA 的公钥创造贡献、前面的秘密会议钥匙。最后,协议的安全被禁令逻辑证明。
This paper reviews the basic content of key management, points out the limitation of the existing key agreement protocols. It introduces RSA public key cryptosystems in detail and homomorphie encryption scheme in the integer ring. The homomorphism key agreement based on RSA is presented. Compared with Diffie-Hellman protocol, its operation speed is more quickly; Compared with key agreement protocol based on password, it has better security. The protocol can use the public key of RSA to create the contributory, forward secrecy the session key. Finally, the security of the protocol is proved by BAN logic.
