摘要: 由于无线网络的开放性,在移动设备和服务器的交互过程中可能存在用户身份及服务信息的隐私泄露问题。为此,提出一种保护移动网络中用户隐私的付费机制。服务器采用密文策略属性加密方法向用户发送请求结果,相比采用传统加密方法更加高效。使用假名实现多用户联合请求某一种或多种服务,在实现隐私保护同时降低用户的成本。分析结果表明,该机制能够保护用户身份隐私,实现通信安全,降低服务器端的计算和通信代价。

Abstract: Due to the openness of wireless network,user identity and service information may leak in the interaction between mobile devices and servers.Therefore,this paper puts forward a payment mechanism to protect the privacy of mobile network users.In this mechanism,servers adopt the method of Ciphertext Policy Attribute Based Encryption(CP-ABE) to send results to users,which is more efficient than using the traditional encryption method.Furthermore,by using pseudonyms,multiple users can make an joint request to get one or more services,which reduces the cost for users while protecting their privacy.Analysis results show that the mechanism can protect the privacy of user identity,realize secure communication,and reduce the cost of server-side computation and communication.
