The Hierarchical Network Security Protocols Designing based on Public Key.

Abstract: This paper proposed a hierarchical network security protocols designing model based on public key, the designing of the protocols is to be completed in several layers. Each sub-protocol achieved a sub-goal that it should complete, and provided data interface to a higher sub-protocol. And then merged the sub-protocol of each layer, to complete the protocols designing. In the previous research, the security of the protocol was always regarded as a whole, which caused the protocols designing to be tremendous complexity. The hierarchical model simplifies the process of security protocols designing, and make the protocols designing more clear or less cost, the security proof more simpler. [Copyright &y& Elsevier]
