摘要
分析和比较了3种可在协同工作中采用的安全机制,包括基于单钥体制、基于公钥体制,以及基于混合方式的安全机制。单钥体制更适合于保密通信,公钥体制更适合于分配单钥体制的密钥,而混合方式则兼有单钥体制及公钥体制的优点,因而更符合协同工作系统对于安全机制的要求。
Three kinds of security methods are analyzed and compared in this paper including symmetric key cryptography,public key cryptography and the hybrid encryption protocol. Symmetric key cryptography is more suitable for data protection in communication, while public key cryptography is more suitable for key distribution. For having the virtue of the two cryptography,the hybrid encryption protocol is put forward,which is fit for cooperative work well.
