Abstract


The modern warfare is a high-technic competition on land, ocean, air, outer space and ele-magnet. The focus of warfare has become to be the battle on the control of information rather than the control of ocean and air. IT is growing to be the key to the construction of modern national security. As a typical application of information technology in military field, the space information network is quite important in real time grasping the situation of battlefield, sharing information resources, raising the efficiency of command and improving the coordinate operation capability. As a result, it has becoming an important problem, which the whole society pays close attention to.Most of the data transmitted on space information network which applied in military field is the confidential data related to the tendency of war situation. Therefore, whether the application of space information network system is feasible or not, is not only based on the development of basic facility, but also closely interrelated to the security assurance ability. From the point view of the theory of information security, authentication is regarded as the first line of defense in all security systems. Without a fine authentication mechanism as the foundation and safeguard, all the other technologies like building a cabinet on air, building a tower on sand. So it has great value on the research of access security technology in space information network.The content of this paper contains the relevant technique of access security, authentication, intrusion tolerance and so on. Firstly, the paper summarizes the current situation and development of the space information network, analyzes the characteristics of the space information network , including highly exposed property, dynamic network formation, switching of access, limit of the communication ability, big scale and wide scope, and proposed a new conception model of the access security system which suitable for the space information network. Then, the thesis designs each module of the system respectively. Here we present the work in three parts: improving the EAP-TLS protocol, putting forward a new trust model to ensure the cross-domain authentication quick and secure, using the intrusion tolerance technology in the trust model in order to improve the survivability and invulnerability of the system. At last, the paper refers the simulating algorithm used openssl and verifies the applicability of the access security system through the comparing the simulated data of typical protocols. The paper also introduces the design of the distributed visualizing simulation platform based on VB and VC for real-time performance of subjects and evaluates the possible attacks in the actual application.
