An Authentication and Key Exchange Protocol for Secure Credential Services

摘要

In this paper, we propose a leakage-resilient and proactive authenticated key exchange (called LRP-AKE) protocol for credential services which provides not only a higher level of security against leakage of stored secrets but also secrecy of private key with respect to the involving server. The LRP-AKE protocol is provably secure in the random oracle model with the reduction to the computational Diffie-Hellman problem.
