An Identity-based Mediated Signature Scheme from Bilinear Pairing
It has always been a critical issue to find efficient methods for fast revocation of a user's identity in identity (ID)based cryptosystems. Unfortunately, none of the previou...

On Perfect and Adaptive Security in Exposure-Resilient Cryptography
Abstract. We consider the question of adaptive security for two related cryptographic primitives: all-or-nothing transforms and exposureresilient functions. Both are concerned with...
