Generic Construction of Certificateless Signcryption Scheme

Jayaprakash Kar and Sagar Naik

Abstract

Confidentiality and message authentication are the most important security goals that can be achieved simultaneously by Signcryption scheme. It is a cryptographic technique that performs both the functions of digital signature and public key encryption in a single logical step significantly at a lower cost than that of conventional method of signature-then-encryption. The paper proposes an efficient Certificateless Signcryption Scheme(CLSC) in random oracle model on bilinear mapping. It is provably secure under the assumptions of intractability of k-CAA, Inv-CDH, q-BDHI and CDH problems.
