引入权重的Ad Hoc网络身份认证簇接入模型

An Improved Authentication Cluster Control Model in Ad Hoc Network

在研究原有的基于身份认证的簇接入模型的基础上,结合shamir门限方案和权重理论,提出了一个改进的Ad Hoc网络身份认证簇接入模型。该模型结合实际情况对簇中的所有成员节点赋予对应的权重值,任意成员节点在认证过程中享有不同的认证地位。即使簇中成员节点数量减少,新节点只要获得t份以上的部分成员身份证书和部分共享密钥仍然能够完成认证,计算自己的身份证书和共享密钥。

The paper studys an intrinsic authentication cluster control model, then an improved authentication cluster control model based on threshold scheme of shamir and the weight theory was presented. The model endows with weighed value to all member nodes in the cluster, any node takes different authentication status. Even though member nodes have reduced, the model do the authenticating if new node could receive more than t share of part member identity certificate and part shared key, then calculate its identity certificate and shared key.
