A certification authority is a trusted third-party entity that provides digital certificates that generate digitally signed and public-key and private-key pairs, primarily to ensure the authenticity and non-repudiation of both parties in the form of a certificate. Because CA certification can guarantee the authenticity of both parties’ information, it plays an important role in data security and e-commerce. In this paper, according to the information security needs of enterprises, this paper studies the technology of establishing enterprise certification authority based on W IN 2003 and builds an enterprise authentication system to realize the certificate management within the enterprise to ensure the security of internal data and information.
