摘要：

We provide the first eCK security model for predicate-based authenticated key exchange (AKE) to guarantee resistance to leakage of ephemeral secret keys. We also propose an two-pass attribute-based AKE protocol secure in the proposed predicate-based eCK security model based on a attribute-based encryption. The proposed protocol has advantages in security against leakage of ephemeral secret keys and the round complexity compared to the previous predicate-based AKE protocol.
