摘要：
In this paper we propose an optimistic fair exchange protocol of Schnorr signatures with a semi-trusted adjudicator In this protocol we enforce the adjudicator accountability in the protocol to relax excessive reliance on the trust of the adjudicator so that the adjudicator only needs to be trusted by the signer We present a security model and then show that the protocol is strong EUF-CMA secure under the standard Discrete Logarithm (DL) assump non in the random oracle model Finally we compare the performance of the fair exchange protocol of Schnorr signatures (C) 2010 Elsevier Ltd All rights reserved
