| Computer networks and the rapid development of information technology enterprises and promote the development of the information society of great progress, but also a lot of the resulting new security problems and risks. As an information system first line of defense, identity authentication information resources is to ensure that only legitimate users visit was an important guarantee.Authentication refers to the computer and network system operator confirmed the identity of the process. Computer systems and computer networks is a virtual digital world, in this digital world, all information, including the identity of the user with a group of information are specific to the data said. How to ensure that the digital identity of the operator is operating this figure as legitimate owners, ie guarantee the physical identity of the operator status with the corresponding figures have become an important issue.The technology based on digital certificates centralized authentication system, use of digital certificates technology, the information system through the interface with the transformation can solve the Network Information System user identification problems. The system is mainly composed authentication module and authority management modules, based on the techniques used by the PKI technology as digital certificate technology. The system put into use, effectively address the following issues: information transmission system security; Network Information System-wide scope of the identity problem; Non-repudiation key operational issues; Internal personnel leapfrog visit malicious tampering with confidential information; System security operational management issues; departments in the exchange of information between the possible security problems.The system platform for the Internet industry in a certain province has been test run showed that the system has good security, reliability, high efficiency, scalability, better information systems solve the security problems faced. |
