Markov game modeling of mimic defense and defense strategy determination

Network mimic defense technology enhances the robustness of active defense through the redundancy,dynamic and diversity as well as the decision feedback mechanism.However,little work has been done for its security assessment and existing classic game models are not suitable for its dynamic characteristics and lack of universality.A Markov game model was proposed to analyze the transfer relationship between offensive and defensive status and the measurement method of safety and reliability of mimic defense,and calculated the offensive and defensive game equilibrium through non-linear programming algorithm to determine the best defensive strategy considering performance.Experiments give a comparison with the multi-target hiding technique and shows that the mimic defense has a higher defensive effect.Combining with the specific network case,the specific attack and defense path for the exploit of the system vulnerability is given and the effectiveness of the defense strategy algorithm is verified.     

Aerospace and defense

The challenge facing the European aerospace community after 1992, integrating members' individual capabilities into a decisively unified, noncontentious entity, is addressed. The two stellar examples of European cooperation in this area, the European Space Agency (ESA) and Arianespace SA, which builds and launches the Ariane rockets, are examined. ESA is a consortium of the national space research agencies of 13 countries and has overall responsibility for the development of Hermes, France's first manned space vehicle. Arianespace has 52 shareholder companies and research organizations in 11 countries; as the first company of its kind, it has captured more than half the world's commercial spacecraft launch-service business. The aerospace industry's biggest question, namely, what will happen in the defense sector, is discussed, focusing on the restructuring resulting from rising arms costs and changing political realities     

Ballistic-missile defense radars

Ballistic-missile defense has been continuously researched in the United States for the past 14 years. The Safeguard system itself is an outgrowth of both the Nike?Zeus system and later ballistic-missile components developed by various government agencies. The classic result of this early work was clear?an ICBM could be intercepted by another missile. Hence, the real controversy concerning the workability of such systems centered around an entirely different problem?the ``high-traffic environment'?or how to make tens to hundreds of near-simultaneous intercepts while tracking thousands of targets. This article describes the radars that have led to a solution of this problem, and how such radars operate within the framework of the world's most sophisticated defense system.

Integrated electronics in defense systems

The role played by the Department of Defense in the early development of integrated electronics is discussed and the current status of military application is summarized. The potential advantages of the new technology to military systems are outlined. These include improved reliability, savings in cost, improved maintenance and logistics supply, enhanced system effectiveness, design flexibility, shorter development/production leadtime and decreased size, and weight and power requirements. The paper concludes with a discussion of the question of military specifications and standards supporting the position that standardization in integrated circuits should for the present be limited to criteria for stating performance characteristics, methods of measuring characteristics and definitions and terminology.
