Design and Implementation of Digital Authentication System Based on PKI
Abstract:In the information age, information has become an important strategic resource. Because of the wide application of computer and network in all areas of society, people’s dependence on computer and network is bigger. Therefore, information security has become a hot society issue and a research hotspot. PKI technology can ensure the confidentiality, integrity and non-repudiation. It is the best technology in the field of network security authentication. This paper introduces the basic theory of cryptography and authentication methods, and elaborated the related technology of PKI; through the analysis of the functional requirements, design a simple small digital authentication system; the system achieved the certificate generation, certificate revocation, certificate update, key management and other functions. Additionally, the SSL protocol is used to establish a secure channel for data transmission to prevent the information eavesdropping in the process of information transmission.
