Optimistic Fair Exchange based on Publicly Verifiable Secret Sharing
2004
Information Security and Privacy. ACISP 2004
In this paper we propose an optimistic two-party fair exchange protocol which does not rely on a centralized trusted third party. Instead, the fairness of the protocol relies on the honesty of part of the neighbor participants. This new concept, which is based on a generic verifiable secret sharing scheme, is particularly relevant in networks where centralized authority can neither be used on-line nor off-line.
