| Abstract | Optimistic protocols for non-interactive fair exchange [16] of digital signatures have recently been designed. Concurrent signatures [2] eliminate the need of a third party but satisfy only a weaker notion of fairness. In this paper, we present an optimistic protocol for non-interactive fair exchange of digital signatures, derived from concurrent signature protocol of [2]. We prove the security of our protocol in the formal model recently proposed by Dodis and Reyzin in [16]. |
