Abstract: Researching on the relevant theories of SSL protocol, based on the construction of campus security information network system, a university network security system model based on SSL virtual technology of PKI identity authentication system is designed. In order to verify the security and effectiveness of the model system, a system simulation environment is constructed. Through simulation analysis, it shows that the system has good security and practicability, and various functional modules can be smoothly implemented, which can ensure the confidentiality of communication data in client side and server side. The model proposed in this paper has a certain reference significance for the construction of university network information system.
