Hierarchical ID-Based Authenticated Key Exchange Resilient to Ephemeral Key Leakage

摘要

In this paper, the first extended Canetti-Krawzcyk (eCK) security model for hierarchical ID-based authenticated key exchange (AKE) that guarantee resistance to leakage of ephemeral secret keys is proposed. Moreover, an two-pass hierarchical ID-based AKE protocol secure in the proposed hierarchical ID-based eCK security model based on a hierarchical ID-based encryption is also proposed.
