Research Of Security About Information Of Web System

Because of the openness and anonymity of Internet, there exist many hidden trouble of security, the key for keep information security is to implement secure information transmission, reliable system identity authentication and some other secure measures. So there require a solution to provide a end-to-end project, it must include encryption ,digital signatures , firewall , VPN , etc. and it can protect information from leak. The digital certificates play a role in the cryptographic, user Authentication digital signatures and other secure techniques, and it can achieve the authenticities, integralities, transactions privacies and non-repudiation that have gotten extensive adoption, This text exactly regards this as the research object, put forward a solution of ensuring security of informationThis text is through to realizing the characteristic and request of identity authentication and information transmitted safely in the environment of the network , Analyze their system structure, proposed that solves the concrete request for the above problem and key problem in the environment of the network , and give the corresponding solution.This text has introduced various kinds of safe practices at first, and tell the characteristic and advantage of various kinds of safe practices from whole, Then describe in detail about the system structure of the digital certificate, then give the corresponding solution, analyze the difficult point and solution in the course of realizing. This text did a summary to the whole systematic realization at last, And take a the application prospect to the system.
