基于MANET可用性的信任度量模型

Availability based trust evaluation model for MANET

提出并设计了基于可用性的信任度量模型(ABTEM,availability based trust evalua tion model),在此基础上可以构建多种针对可用性的安全服务。网络模拟实验的结果证明,将ABTEM应用于DSR路由协议时,在路由层能够成功地根据其恶意行为发现网络中的恶意节点,并且进一步孤立这些恶意节点,从而避免网络继续受到恶意节点的侵害,显著提高了MANET系统的可用性。

ABTEM was presented, an availability based trust model, and many availability oriented security service can be obtained based on this model. The performance results show that malicious nodes can be successfully discovered in accordance with its malicious acts in the routing layer when apply ABTEM on the DSR protocol. Furthermore malicious nodes can be isolated to protect the network from the attack of them, and which will significantly increases system avail- ability.
