    Abstract

    Recently, Libert and Quisquater showed that the fast revocation method using a SEcurity Mediator(SEM) in a mRSA can be applied to the Boneh-Franklin identity based encryption and GDH signature scheme. In this paper we propose a mediated identity based signature(mIBS) scheme which applies the SEM architecture to an identity based signature. The use of a SEM offers a number of practical advantages over current revocation techniques. The benefits include simplified validation of digital signatures, efficient and fast revocation of signature capabilities. We further propose a forward mediated signature scheme with an efficient batch verification and analyze their security and efficiency.
