Research on Applied-Information Technology in Hierarchical Network Security Protocols Designing Based on Public Key

Abstract

This paper proposed an applied-information technology in 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 in applied-information technology was always regarded as a whole, which caused the protocols designing to be tremendous complexity. The hierarchical model in applied-information technology simplifies the process of security protocols designing, and make the protocols designing more clear or less cost, the security proof more simpler.
