The Research And Application Of The PKI Technology In The Military Network

With the rapid development of Internet /Intranet technology, information transmission by using the Internet is becoming the key way to improve tactical command and the working efficiency in the army. Network system has become the kernel and key of army construction change from mechanization to information. It became the attention focus of all levels military affairs commander how to transmit the information safely. Many nations in the world have researched for many years to solve Internet/Intranet security problem and form a integrated project, PKI technology (Public Key Infrastructure) The certificate authority, which is based on the Public Key Infrastructure, is thought to be the efficient method to solve the problem of information security. In order to ensure the information security, the users can encryption and signature the transmitting data information by using the Data Certificate, which is issued by the certificate authority.This article combines the details of information network system of a certain motorization infantry division, discusses the design and realization of MTHSCA, which is based on public key infrastructure and supplies the safety support technology for the automatic office system.First of all, the article discusses some normal kinds of encryption technology. Through the analysis of encryption, it introduces the basic principles of public key infrastructure and emphasizes on the RSA and its safety.Next, the article introduces the certificate authority and its authentication and discusses the digital signature user identification and Public key authentication. Therefore, these authentications supply the theoretical support for the establishment of the certificate authority of MTHSCA.Finally, the article mainly introduces the design and realization of the certificate authority of MTHSCA. The system use windows 2000 as the software platform and develops systematically by using the certificate services. The system structure of certificate authority and the function modules of the system are introduced in the system structure part. Therefore the article introduces the detailed methods of establishing certificate authority and the establishment of data certificate. Meanwhile, the article discusses the actual functions of digital certificate in office automatic system on web, and the key management security of the digital certificate.
