Abstract
In this paper, we substantially modify Hung et al. [1] Anonymous Multi-receiver Certificateless Encryption (AMCLE) scheme to a Multi-receiver Certificateless Signcryption (MCLS) scheme, which provides authentication and introduces public verifiability as an additional feature. We show that, as compared to existing signcryption, our scheme requires less computation for the signcryption and unsigncryption phases. Additionally, the signcryption cost is linear with the number of designated receivers, while the unsigncryption cost remains constant. We compare the results with existing single-receiver and multi-receiver signcryption schemes and show that our proposed MCLS scheme is more efficient for single and multi-receiver signcryption schemes while providing an exemption from the key escrow problem and working in certificateless public key settings.
