Chameleon signatures are non-interactive signatures based on a hash-and-sign paradigm, and similar in efficiency to regular signatures. The distinguishing characteristic of chamel...

We construct two efficient Identity Based Encryption (IBE) systems that are selective identity secure without the random oracle model. Selective identity secure IBE is a slightly w...

Abstract. In this paper, we give a first example of identity based undeniable signature using pairings over elliptic curves. We extend to the identity based setting the security m...
