The Design And Research Of Secure Communication About Cop

COP is visible expression of war field and situation of enemy and us, which can provide state of war field, action and information of environment for army. By Common Joint Operat- ional Picture,campaign and decision-making personnel can know development of situation of campaign in real time or almost,who quickly,correctly and confidently intercommunicate ca- mpaign purpose,moreover, who implement command and control correctly, high–effect ly and duly. So, cop is very important for all campaign army that can accomplish apperceive of situ- ation and cooperative programming for victory of war. How to achieve secure share of cop in Joint Operations is very important and urgent problem of our army.In this paper, we have studied cop, IPsec VPN technology, multicasttechnology, trusted computing technology and middleware technology. And we designed secure communication of cop.The main work of this paper is as follows:1. Summarized Common Operational Picture.Pointed out application and security dema- nd of COP for our army.2. Summarized the development of IP-VPN technology.Introduced emphasisly IPsec VPN technology.3. Put forward secure communication of IPsec VPN based on trusted computing, which ensures creditability of communication terminal and security of transferring Common Opera- tional Picture on campaign and command network.Put forward vpn process based on conn- ection track, which improves the speed of the process of packet greatly because policy lookup only relates the times of connection.At the same time, it builds up the security of Communic- ation system.4. Put forward security communication of VPN gateway based on multicast.It makes campaign personnel and commander notify all joint operation personnel duly, quickly, corr- ectly and securely when they discover new thing of campaign, which can acommplish share of situation for victory of campaign.
