Research and Implementation of Enterprise CA System Based on PKI

With the rapid development of e-commerce in recent years, it brings unlimited opportunities for people, but it also gives people a very serious subject, namely, how to ensure security of network. applications. The PKI is a technology platform that can be used to address the problem of e-commerce security effectively. This paper presents a self-built CA system model for enterprise based on PKI, We describe the overall structure and design model in detail, and give specific implementation methods. Compared with other CA system, some features of this system include: open source code based, low cost to achieve, implementation of database technology, excellent compatibility with other enterprise application systems, realization of dual key pairs, separating the signature / authentication key pairs from encryption / decryption key pairs. This enterprise´s CA system can preferably solve the authentication, sensitive data transmission and other issues of network security, and promote the process of e-commerce. the application has broad prospects.
