Abstract
The first provably secure identity-based undeniable signature schemes was proposed by Libert and Quisquater, where they formulated the security model of undeniable signature schemes in an identity-based setting for the first time. Later, Wu et al. proposed a convertible identity-based undeniable signature scheme. Both of the proposed schemes require pairing evaluations in their signing algorithm. In this paper, we propose an efficient identity-based undeniable signature scheme and prove its security in the random oracle model. Due to its efficient signing algorithm and short signature length, our scheme can be applied to systems with low-computation power which are operating in low-bandwidth communication channels (e.g. mobile phones, PDAs, etc.).
