| 摘 要： | 传感器网络面临的攻击很多,尤其是内部节点进行的攻击带来的危险最大。同时,传感器网络特别是军用传感器网络不能采用建立信任中心的信任模型,导致其内部节点的恶意行为更难以控制。通过引入基于CPK认证的源地址认证模块,使用第三方推荐信任,并结合多种相关的网络行为属性,能够为用户提供更准确可信的信任度计算能力作为参考依据,使用户可以根据信任度对权限进行控制,以达到控制恶意行为的目的。

| Abstract: | There are too many kinds of attacks against sensor networks, and the most dangerous are the attacks from interior. Under a hostile military environment, a sensor networks with a trust model which adopt the central trust authority can be easily attacked by malicious nodes and hostile nodes. In this paper, we introduce the trust mechanism with a Source Address Validation module and combines all kinds of trust values together, including the direct trust and indirect trust value of nodes. Some attributes are also introduced to calculate the direct trust value. |
