摘　　要：针对无线移动网络WMN(Wireless Mobile Networks)易受攻击的问题,提出一种基于令牌的无线移动网络隐私保护和认证TPPA(Token-based Privacy Preserving and Authentication)协议。在协议中令牌通过基站选择的虚节点在发送器和接收器之间传送消息,该协议使用签名加密算法对包含查询UE的伪身份的身份验证请求进行签名,从而为UE提供匿名性。服务基站(SeNB)通过安全通道从UE接收注册请求后,为UE生成伪身份及其对应的私钥。UE使用签密向SeNB发送查询请求消息。该消息由SeNB的ID、UE的伪ID和哈希函数组成,SeNB通过执行无符号隐藏来检索消息。该协议可以有效地保护用户的隐私并减少控制开销。实验结果表明,与PPNNQ相比,该算法在保证隐私保护的前提下,减少了平均端对端延迟,提高了平均包传递率,减少了丢包数量和通信开销。Wireless mobile network(WMN)is vulnerable to be attacked,so we proposes token-based privacy preserving and authentication(TPPA)protocol.In the protocol,the token transmitted messages between the sender and the receiver through the virtual node selected by the base station.The protocol adopted the signature encryption algorithm to sign the identity verification request including the pseudo identity of the querying UE,thereby providing anonymity to UE.After receiving the registration request from the UE through the secure channel,the serving base station(SeNB)generated a pseudo identity and its corresponding private key for UE.UE sent the query request message to SeNB using the signcryption.The message consisted of the ID of SeNB,the pseudo ID of UE,and hash function,and SeNB retrieved the message by performing unsigned hiding.The protocol effectively protected user privacy and reduced control overhead.The experimental results show that compared with PPNNQ,the proposed algorithm reduces the average end-toend delay,improves the average packet transfer rate,and reduces the number of lost packets and communication overhead under the premise of ensuring privacy protection.
