Abstract
In this paper, we show how to construct an Identity Based Signcryption Scheme (IBSC) using an Identity Based Encryption (IBE) and an Identity Based Signature (IBS) schemes. We show that the security of the IBSC scheme-indistinguishability as well as unforgeablity-is derived from the security of the underlying IBE and IBS schemes. Moreover, we show that under mild (reasonable) assumptions, the scheme is both space and time efficient compared to the Sign-then-Encrypt approach. © 2011 Springer-Verlag.
