Abstract

Abstract

In cloud computing applications, it is very important to ensure the confidentiality and unforgeability of messages, while judging the equivalence of different ciphertexts to plaintexts. The signcryption scheme with equality test can achieve the above security goals. Based on the certificateless public key cryptography environment, a Certificateless SignCryption scheme with Equality Test (CLSCET) is designed. Firstly, the framework and security model of the certificateless signcryption with equality test scheme are proposed, moreover two types of adversaries with different attack capabilities and three types of security targets are defined. Secondly, a specific certificateless signcryption with equality test scheme is constructed, and the correctness of the scheme is analyzed. Finally, based on the random oracle model, it is proved that the scheme satisfies the security properties of One-Way against Chosen Ciphertext Attack(OW-CCA), INDistinguishability against adaptive Chosen Ciphertext Attack(IND-CCA2) and Existential UnForgeability against adaptive Chosen Message Attack(EUF-CMA). Compared with the existing approximate schemes, the scheme satisfies the confidentiality of IND-CCA2, the unforgeability of EUF-CMA and the one-way ciphertext of OW-CCA.
