Abstract
Signcryption offers authentication and confidentiality simultaneously with a lower cost.A new identity based signcryption scheme is proposed,which is proved to be secure under the random oracle model.The proposed scheme does not require pairing operation in signcryption,and only have 2pairing operations in unsigncryption.Compared with the previous schemes,the computation cost of the proposed scheme is less.
