Efficient Identity Based Signature in Standard Model

S. Narayan

Abstract

In this paper, we present an efficient signature scheme without random oracles using Waters private key construction. Our scheme has shorter public parameter size when compared to Kenny and Schuldt signature, the signature space of our basic scheme consists of three group elements, we further show that the signature space can be reduced to two group elements. The security of our signature scheme is proved in the standard model under adaptive identity security notion.
