基于概率博弈的空天地一体化网络安全路由算法

Secure Routing Algorithm Based on Probabilistic the under Space-Air-Ground-Integrated-Network

针对空天地一体化网络存在的安全问题,提出了使用路由证据的方法对洪泛攻击、灰洞/黑洞攻击进行防御的方案。该方案可以检测出自组织网络中存在的恶意节点,以保证路由的安全可靠性;克服了已有方案存在的不足,可以自适应地在空天地一体化网络等容断容迟网络中应用。此外,搭建了仿真平台,通过仿真验证的手段,证明了该方案可以检测出90%以上的恶意节点,验证了其有效性。

To solve the security problems in the space-air-ground integrated network,this paper proposed a scheme using routing evidence to defend against flooding attacks and grey hole/black hole attacks.The scheme can detect malicious nodes in the ad-hoc network to guarantee the security and reliability of routing.It resolved the shortcomings of the existing schemes and could be adaptively applied in the interruption and delay tolerant network such as the space-ground integrated network.A simulation platform was built in this study,and according to the verification,the proposed scheme can detect more than 90%of the malicious nodes,proving its significant effectiveness.
