Identity-Based Signcryption
Abstract
A signcryption scheme is a scheme that provides private and authenticated delivery of messages between two parties. It does this in a more efficient manner than a straightforward composition of an encryption scheme with a signature scheme. An identity-based cryptosystem is one in which the public key may be any string (or may be derived from any string). In this paper we propose an identity-based signcryption scheme. We give a security model for such a scheme and sketch the details of how our scheme may be proved secure in this model.
