Bing Zhang · Modern Electronic Technique · 2005
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.
