Title:
A New Short Signature Scheme Without Random Oracles from Bilinear Pairings
Authors: Fangguo Zhang, Xiaofeng Chen, Willy Susilo, Yi Mu
Abstract:In this paper, we propose a new signature scheme that is
existentially unforgeable under a chosen message attack without random oracle. The security of our scheme depends on a
new complexity assumption called the k+1 square roots
assumption. We also discuss the relationship between the k+1
square roots assumption and some related problems and provide some
conjectures. Moreover, the k+1 square roots assumption can be
used to construct shorter signatures under the random oracle
model. As some applications, a new chameleon hash signature scheme
and a on-line/off-line signature scheme and a new efficient
anonymous credential scheme based on the proposed signature scheme
are presented.
