An identity-based ring signature scheme from bilinear pairings

Chih-Yin Lin and Tzong-Chen Wu

Abstract: At the conference Asiacrypt 2001, Rivest, Shamir and Tauman firstly addressed the concept of ring signature. In this paper we propose an identity-based ring signature scheme from bilinear pairings. As compared with the Zhang-Kim scheme (presented at the conference Asiacrypt 2002), our scheme is more efficient in computation and requires fewer pairing operations.

Category / Keywords: cryptographic protocols / ring signature, identity-based, bilinear pairings.
