Abstract

Certificateless aggregate signcryption not only can ensure the confidentiality and authentication of information transmission, but also can reduce the cost of data communication and the verification of ciphertexts. Through analyzing some existing certificateless aggregate signcryption schemes, it is found that their efficiencies are much lower. A provable secure certificateless compact aggregate signcryption scheme is proposed in this paper. In the new scheme, the pairing numbers, not depending on the number of signcryption users, are constant when aggregate ciphertexts are verified. Compared with the existing certificateless aggregate signcryption schemes, the new scheme decreases pairing numbers and raise the efficiency of verification. Moreover, based on the assumption of bilinear Diffie-Hellman and computational Diffie-Hellman, in the random oracle model, it is proved that the new scheme satisfies the properties of confidentiality and unforgeability.
