An improved certificateless signcryption scheme

Open publisher page 1 citations

Abstract

A certtificateless signcryption (CLSC) scheme is an important primitive in cryptographic protocols which provides the goals of signing and encryption, simultaneously. In 2010, Liu et al presented the first certificateless signcryption scheme in the standard model, but their scheme is vulnerable against different attacks presented in the literature, till now. In this paper, we will improve their scheme and propose a new certificateless signcryption scheme in the standard model.
