军用无线网络动态安全防御技术研究

随着军用无线网络的发展,安全问题变得越来越重要。但军用无线网络主要因循互联网体制,所采用的体系结构在设计之初就没有过多考虑安全问题,存在本质上的不安全因素,而通过“打补丁”附加安全机制的方式,使得当前的安全系统和网络变得越来越臃肿,严重地降低了网络性能。动态目标防御(moving target defense,MTD)理论的提出,彻底颠覆了过去那种静态、被动的安全防御思路,这种革命性的思路与无线网络协议的深入结合,将带来全新的网络体系,特别是它的很多思路与无线网络特性具有高度耦合性,将在未来军用无线网络中得到广泛的应用。

Dynamic Security Defense Application on Military Wireless Network

With the development of military wireless network, system security becomes even more important. However, the military wireless network always follows the principle of Internet, and its adopted architecture lacks security consideration in the beginning of design, thus in these systems exist essentially insecure factors. The traditional security mechanism usually posts security patches on the existing system, thus making the current security system and network more redundant, and leading to severe decrease of the network performance. The theory of MTD (Moving Target Defense) is proposed to completely change the traditional static and passive security defense mode. The thorough combination of revolutionary MTD technology with wireless network protocols would bring novel network architecture. In particular, many ideas of MTD technologies,for being highly coupled with the characteristics of wireless network,would be widely applied to the future military wireless network.
