| 摘 要： | 证书授权（Certification Authority，CA）的价值表现在权威和技术两个方面，典型的CA认证中心为保证CA的权威性花费了巨大的建设和运营成本。企业应用的特点决定了企业CA可以适当放弃CA的权威性而重点利用CA的技术来解决应用系统的安全问题，自助型CA就是针对企业应用系统的具体情况对CA的简化。在自助型CA认证中心中，没有RA（Register Authority）和独立的证书库，只保留CA服务器，可以随时签发证书，并且与企业应用的访问控制系统融为一体，使用方便，建设和运营成本很低。

| Abstract: | The value of CA depends on two aspects, authority and technology. Ordinary CA costs most on construction and maintenance in order to insure its authority. Enterprise CA can decrease its authority and focus on utilization of its technology to deal with security problems in application system because the character of enterprise application. Self-help CA is just a type of simplified CA that adapted to enterprise application. Self-help CA disposes RA and independent certificate database only reserve CA Server and can sign certificates at any moment. Self-help CA can be integrated with access control system of application and is easily used, cost in construction and maintenance is lower. |
