Abstract

In this paper, we present a new identity-based signature scheme with message recovery based on bilinear map. Our scheme is proved secure against existential forgery on adaptive chosen message and ID attack under the random oracle model. This new scheme shortens the total length of the original message and the appended signature and adapts to the ubiquitous network scenario very well.
