随着网络信息技术的发展,信息的完整性、机密性、身份鉴别和不可否认性越来越重要。CA是PKI的核心,是具有权威性、可信任性、公正性的第三方机构,通过向用户颁发公钥证书,将用户身份信息与所持有的公钥相互绑定。利用OpenSSL开源软件实现基于PKI的CA系统,系统具有根证书下载安装、用户证书申请、颁发、撤销等功能。所发布证书遵守X.509标准。提出可行的应用于企业办公系统的基于PKI的CA系统。
With the development of network information technology, the integrity, confidentiality, identity authentication and non-repudiation of information are more and more important. CA is the core of PKI. It is an authoritative, trustworthy and impartial third-party organization that binds user’s identity information and public key by issuing public-key certificate to users. OpenSSL open source software using PKI-based CA system, the system has a root certificate download and install, user certificate application, issuance, revocation and other functions. The issued certificate complies with the X.509 standard. Put forward feasible PKI-based CA system which is used in enterprise office system.
