随着Internet技术的发展,Intranet服务、电子商务、网络银行成为近年来的几大热点,国内也有越来越多的机构、企业涉足这些领域。这样,信息安全问题就提到日程上来。几年来,在Internet上涌现出了许多新的安全技术和安全规范,公开密钥基础设施(PKI:Public Key Infrastructure)即是其中一员。 一、PKI的基本组成 PKI是一种遵循标准的密钥管理平台,它能够为所有网络应用透明地提供采用加密和数字签名等密码服务所必需的密钥和证书管理。 从广义上讲,所有提供公钥加密和数字签名服务的系统,都可叫做PKI系统, With the development of Internet technology, intranet services, e-commerce and internet banking have become the hot topics in recent years. More and more domestic agencies and enterprises are involved in these fields. In this way, information security issues mentioned on the agenda. Over the years, many new security technologies and security specifications have emerged on the Internet, including the Public Key Infrastructure (PKI). First, the basic composition of PKI PKI is a standard-compliant key management platform that provides transparent encryption and digital signature for all network applications such as cryptographic services required key and certificate management. Broadly speaking, all systems that provide public key cryptography and digital signature services can be called PKI systems,
