PKI技术运用了公钥技术与原理,提供了通用性的安全服务,实现了安全基础设施拥有通用性,随着互联网在飞快的发展,不断出现新的技术,并且技术也越来越假成熟,例如:PKI的体系结构应用广泛。本文章概述了PKI,分析了PKI的组成,研究了其核心服务,并提出PKI技术在安全电子商务系统中的应用,对PKI技术在企业电子商务中所存在的问题和处理措施进行了探究。以计算机网络安全作为基础,实现了电子商务信息的安全,建设起一个相对来说可靠、方便快捷、安全的电子商务环境,可以更可靠、更完善的来保护信息。互联网在快速的发展,使得不断 PKI technology uses the public key technology and principles, providing universal security services to achieve a common security infrastructure, with the rapid development of the Internet, continue to emerge new technologies, and technology is more and more fake, For example: PKI architecture widely used. This article gives an overview of PKI, analyzes the composition of PKI, studies its core services, and puts forward the application of PKI technology in secure e-commerce system. It also probes into the problems and countermeasures of PKI in e-commerce. With computer network security as a foundation, the e-commerce information is safeguarded and a relatively reliable, convenient and safe e-commerce environment is built so as to protect information more reliably and completely. The rapid development of the Internet, making continuous
