Research and Design of Dynamic Migration Access Control Technology Based on Heterogeneous Network

Abstract

Abstract:With the continuous development of wireless networks, the amount of privacy services in heterogeneous mobile networks is increasing, such as information storage, user access, and so on. Access control security issues for heterogeneous mobile radio network, this paper proposes a dynamic migration access control technology based on heterogeneous network. Through the system architecture of the mutual trust system, we can understand the real-time mobile node failure or abnormal state. To make the service can be terminated for the node. And adopt the 802.1X authentication way to improve the security of the system. Finally, it by combining the actual running test data, the trust update algorithm of the system is optimized to reduce the actual security threats in the environment. Experiments show that the system's anti-attack, the success rate of access, bit error rate is in line with the expected results. This system can effectively reduce the system authentication information is illegally obtained after the network security protection mechanism failure and reduce the risk of user data leakage.Keywords: Heterogeneous network; wireless network; mutual trust system; trust update algorithm IntroductionThe diversification of Internet services and the spread of Because heterogeneous network services are the interaction between users and service delivery systems, service security is based on mutual trust between them. The user terminal can access the service providing system simultaneously through a different access network. When the authentication information of the only legitimate user is illegally stolen by another person, the service providing system cannot distinguish whether the object to be accessed is a legitimate user. As a result, there is a security issue for the mutual authentication system of authentication between the user terminal and the service providing system.
