摘要
分析了移动自组网的特点及其对身份认证机制的安全需求,针对在分布式门限认证中如何让证书适时有效更新,提出了一种基于权值的移动自组网门限证书更新方案。分析表明,该方案通过引入节点间的相互监督机制,可将恶意节点及时分离出去,同时在一定程度上可防止同谋攻击。
The characteriscs and the security requirement of the identity authentification mechanism of ad hoc network is analized. In a distributed threshold certificate authentity system, in order to timely and effectively update the certificates, a novel certificate updating scheme based on weight and threshold is proposeed. Analisis indicates that it could timely and effectively separate the malicious nodes, at the same time could prevent the conspiracy attacks to some extent.
