An Identity based Multi-receiver Generalized Signcryption Scheme

Generalized signcryption can adaptively work as a signcryption scheme, a signature scheme or an encryption scheme jointly with only one algorithm. It is very suitable for the storage constrained environments, like smart card, the embedded system and wireless sensor networks. In this paper, we proposed an identity based multi –receiver generalized signcryption. We also prove the security of the proposed scheme in the simplified modal under the q-DHIP and q-BDHIP.
