摘要
在自组网的匿名通信中,节点通常用伪身份来代替节点的真实身份进行通信并不断变更伪身份,从而达到隐藏节点真实身份的目的。由于一般的基于双线性映射的签名方案在匿名通信中,签名对私钥生成器(PKG)不是匿名的,因为PKG可以生成任意伪身份对应的私钥。提出一个应用于自组网匿名通信的基于双线性映射和伪身份的签名方案解决上述问题。最后,对该方案进行了正确性、匿名性和安全性分析。
In order to hide the identities in anonymous communication in Ad Hoc networks, the nodes use the pseudonyms to replace the real identities of the nodes. A pseudonym-based signature scheme from bilinear pairing was proposed for anonymous communication in Ad Hoc networks. The new scheme can solve the problem: the anonymous communication is not blind to Private Key Generator (PKG) and the PKG can forge the nodes' signature using the pairing- based signature scheme in the anonymous communication. At last, the correctness, pseudonym and security of the new scheme were analyzed.
