Research On Implementation Scheme Of Mail System Deployment Based On PKI

More and more companies attach great importance to the development of information technology and security,so that E-mail technology become an important tool for ensuring the rapid and efficient exchange of large amounts of information.However,it has also become a key target for attacks because of its universality.How to solve the problem of confidentiality,integrity,and non-repudiation of data in the process of transmission becomes very urgent.This paper takes the public key infrastructure as the technical foundation and focuses on the design and development of the interface between the email system and the certification center.It summarizes the development specifications of the interface for unified user synchronization,single sign-on,and identity authentication interfaces,which includes the scope of the development environment,the specification of interface return values,the identification of unique attributes and the acquisition of error information.At the same time,in order to ensure the safe and stable operation of the developed interface,the performance and security of the mail system were tested in the unit network environment.This work realized not only the identity authentication and single sign-on of the mail system,but also the design criteria and reference basis for the development of other application systems and authentication center CA interfaces.The corresponding test work proves that the security and confidentiality of the mail system can meet the actual needs of the unit.
