主 题：public-key encryption identity-based hash proof system lattice updatable leakage-resilience
摘 要：Identity-based hash proof system is a basic and important primitive. Ittographic schemes and protocols that are secure against key-leakage attacks. In thisupdatable identity-based hash proof system, in which the related master secret keyis widely utilized to construct cryp-paper, we introduce the concept ofand the identity secret key can beupdated securely. Then, we instantiate this primitive based on lattices in the standard model. Moreover, we introduce anapplication of this new primitive by giving a generic construction of leakage-resilient public-key encryption schemes withanonymity. This construction can be considered as the integration of the bounded-retrieval model and the continual leakagemodel. Compared with the existing leakage-resilient schemes, our construction not only is more efficient but also can resistmuch more key leakage.
