Abstract: According to anonymous request in communications process of mobile Internet, an anonymity communication protocol based on signcryption and trusted computing was proposed to resolve the problem of anonymous communications in mobile terminal. In this model, the forwarding nodes could identify the integrity of the received information and the validity of the forwarding path according to the signcryption of previous nodes. The research results reveal that the protocol has a good security and trusted anonymous property, which achieves the anonymous communication process of safety requirements for mobile terminals.

摘要： 针对移动互联网对通信过程的匿名性需求，提出基于签密和可信计算技术设计移动互联网下的匿名通信模型,以实现通信双方间的匿名通信。该模型中，中间节点根据前驱节点的签密信息鉴别转发数据的完整性，验证转发链路的真实性。分析表明该模型在实现通信匿名的同时具有安全性与可信性，满足移动互联网下移动终端匿名通信过程的安全需求。
