An Efficient ID-based Signature Scheme from Pairings

Chunxiang Gu and Yuefei Zhu and Xiaoyu Pan

Abstract: In this paper, we propose an efficient ID-based signature scheme based on pairing. The number of paring operation involved in the verification procedure is one. Our scheme is proved secure against existential forgery on adaptively chosen message and ID attack under the hardness assumption of computational Diffie-Hellman problem, in the random oracle model.

Category / Keywords: public-key cryptography / ID-based signatures, pairings, provable security, Forking Lemma.
