摘　　要：针对目前远程认证方案中存在的配置信息易泄露、证书管理复杂等缺陷,在属性认证思想的基础上提出了一种基于属性的Chameleon远程认证方法。该方法采用Chameleon hash函数对认证过程进行改进,利用Chameleon hash函数的抗碰撞性对平台配置信息进行保护,并用Chameleon哈希计算结果作为平台属性凭证进行远程认证。分析结果表明,该方法增强了远程认证的灵活性与安全性。Considering the drawbacks of the recent remote attestation schemes, such as easy exposure of the platform configurations information, the complexity of the attestation certificates management, a method property-based Chameleon remote attestation is proposed based on the idea of property-based attestation. PBCRA uses Chameleon hash function to improve the attestation process, and uses the anti-collision character of the Chameleon hash function to protect the platform configuration information, the results of Chameleon hash function are untilzed as the prove of platform attributes in the remote attestation process to address the issues caused by attestation certificates. Analysis shows that the method enhances the flexibility and security of the remote attestation.
