摘要/Abstract

摘要：

针对已有基于谓词的认证密钥交换协议在隐私保护方面的不足，通过结合一个内积加密方案和NAXOS技巧，提出了一个全新的基于谓词的认证密钥交换协议。并在修改的eCK模型下，将协议的安全性归约到了GBDH假设，同时，由于继承了内积加密方案隐藏用户属性的安全性质，新协议能够防止用户敏感信息的泄露。

Abstract:

To overcome the problem that available predicate-based authenticated key exchange(PBAKE)protocols had drawback on privacy protection,a new PBAKE protocol was presented.The new protocol was constructed via combining an inner product encryption scheme with NAXOS technique.The security of the new protocol could be reduced to GBDH assumption in the modified eCK model.At the same time,for inheriting the security property of attribute-hiding from the inner product encryption scheme,the proposed protocol guarded against disclosure of users’ sensitive information.
