摘　　要：为解决ad hoc网络中的匿名认证问题,将民主签名与无中心的秘密分享方案相结合,提出一种无可信中心的门限追踪ad hoc网络匿名认证方案。方案的无中心性、自组织性很好地满足了ad hoc网络的特征,从而解决了传统网络中匿名认证方案由于需要可信中心而不适合ad hoc网络的问题;方案中认证者的匿名性、可追踪性和完备性(不可冒充性)满足了匿名认证的安全需求。In order to provide anonymous authentication for ad hoc network, democratic group signatures with centefless secret sharing scheme and proposed a threshold traceability anonymous authentication scheme without trusted center for ad hoc network were combined. The scheme was centerless and self-organized, which was well suited to the characters of ad hoc network and had solved the problem that those schemes of traditional network were not suited to the ad hoc network. The prover of the scheme was anonymous, traceable, and complete, which well satisfied the security of anonymous authentication.
