Abstract

To put restrictions on signing capability of the proxy signer, the notion of one-time proxy signature was put forth by Kim et al. in 2001. Today, to our best knowledge, although plenty of one-time proxy signature schemes have been proposed, no ID-based one-time proxy signature (IBOTPS) has yet been presented. Therefore, in this paper, to fill this void, we first formalize the security notions for IBOTPS, and propose the first efficient IBOTPS scheme based on the bilinear pairings and provide the formal security proofs in the random oracle model. Also, we consider an application of the proposed scheme in E-cheque scenarios.
