摘要
为了防止恶意用户对车联网云平台进行欺骗,提出通过远程证明对用户属性和可信平台状态进行验证的方案.一方面,采用模糊属性签名方案可以确保终端的匿名性,避免用户身份及隐私信息泄露;另一方面,采用本方案可利用终端的可信模块及可信链传递机制,从而确保硬件、固件及软件的可信性和时效性.此外,在远程证明方案中,向车联网云平台的管理模块申请前用户先提供其行为预测方程,并且云管理模块将一段时间后的行为特征值组与预测方程进行比对,由此确定用户运行程序的动态可信性.采用该方案可有效实现对车联网云用户的远程证明.
In order to prevent malicious users to deceive,the remote attestation scheme was proposed by validating user′s attributes and platform status.On one hand,the scheme can ensure anonymity of the terminal platform,which avoid the user′s identity and privacy information leakage.On the other hand,the scheme can make full use of the trusted platform control module and the trusted chain,to verify the hardware and firmware of the terminal and to verify reliability and efficiency of the software.In addition,user′s prediction equation on behavior firstly was provided,which applied to vehicular cloud（VC）management module,and then the management module would compare user′s real behavior and the prediction equation to get user′s plausibility in the dynamic environment.The scheme realizes the user′s remote attestation on VC efficiently.
