[Abstract]:With the rapid development of mobile communication, many countries have studied the fifth generation of mobile communication technology (5G), but the related security technology research is lagging behind. 5G network security system has put forward higher requirements for security. It is necessary to provide higher and more levels of security mechanism and a more diversified network security solution. Based on the Ad Hoc network, this paper focuses on the cross layer cooperative security technology in the combination security theory of 5G mobile communication system. Through the in-depth analysis of the characteristics and security problems of the Ad Hoc network, the necessity of the cross layer design of the Ad Hoc network is expounded. Then, on the basis of the existing cross layer design scheme of the existing Ad Hoc network, the physical layer is from the physical layer. The link layer, the network layer and the application layer deeply study the existing security threats and vulnerabilities and find the key problems that need to be solved. Then, based on the concept of cross layer design and highlight the concept of cooperative security, a top-down cross layer cooperative security protection mechanism is designed. In the specific design of the scheme, the physical layer security is the first step. The security capacity of communication nodes is calculated, the perfect secret channel is constructed, and the adaptive physical layer key exchange scheme is used to complete the security generation and exchange of the physical layer key. Secondly, the characteristics of the physical layer key generation efficiency are low and the bit error rate is high, and the self synchronization sequence cipher technology is used to expand the physical layer key, and the design is efficient. The system cross layer key generator is used to realize key cross layer use. Finally, it combines the system communication protocol of network layer and application layer to strengthen the security of various system communication protocols by using the system key sequence of physical layer key as the seed, avoiding most of the mainstream network protocol attack methods. Finally, this paper through cross layer cooperative security. The design has solved the key technical problems of system key management, communication security and so on. It realizes the system cooperative security protection from bottom to top, and constructs a cross layer cooperative security defense system of Ad Hoc network.
