Abstract
The idea of aggregate signcryption was first proposed by Selvi. The aggregation process reduces the communication overhead and hence, it is efficient in low-bandwidth communication networks such as wireless sensor networks and vehicular ad-hoc network VANET. The goal of this study is to propose a secure provably identity based aggregate signcryption scheme ID-ASC without pairings over the elliptic curve cryptography. The proposed scheme is provable secure against confidentiality and unforgeability under random oracle model. Moreover, the proposed ID-ASC reduced the computational complexity when compared to other schemes in literature.
