In this paper, we study the construction of verifiably encrypted signature in certificateless public key setting. We first present the notion and the new security model for certificateless verifiably encrypted signature (CLVES) and then present a concrete CLVES scheme based on Zhang's certificateless signature (CLS), and provide the security analysis for the proposed scheme. It proves that our CLVES scheme is secure in the random oracle model by assuming the intractability of the Computational Diffie-Hellman Problem.
