无线自组织网络中一个组匿名通信方案

Group-based Anonymous communication Scheme for Wireless Ad Hoc

为了满足Ad Hoc网络的一些应用场合对身份匿名的要求,如自组匿名电子选举、自组匿名民主评议委员会等,提出一个身份匿名方案。首先,要匿名通信的节点组建一个通信组,再用它们的真实身份协商出一个秘密组密钥和组参数。然后,根据协商出来的秘密组参数各自生成自己的组内可认证的组身份,最后以该组内身份进行组内通信。同时给出了组更新和组内身份匿名撤销的方案,并对整个方案进行了安全性和匿名性分析。

This paper is to offer a new scheme of identity anonymity accordance with the need of identity privacy under certain circumstances, such as anonymous E - vote, anonymous E - commerce, anonymous E - auction, anonymous conference and so on. First, the key and parameter of a communication group of anonymous i- dentities are required on the basis of forming a secret group with their real identities under consultation; then, the approvable identities within this group wilt be created automatically according to the parameter; and thus, mem- bers of this group can communicated with each other anonymously. In this paper, the update in group, the revoca- tion of identity, the safety and the anonymity of this plan are also provided.
