....both parties receive what they expected or nobody gains anything valuable. However, this kind of fairness has to be realized with a trusted third party (also called trustee or TTP) as protocols without a TTP (e.g. EGL82,BOGMR90, Jak95, BN00] cannot guarantee this strong notion of fairness [EY80]. A simple fair exchange solution is an active TTP that is involved in every exchange (e.g. BP90, Tyg96, CHTY96, ZG96, FR97] Much more e cient are optimistic protocols [ASW97] in which the TTP only has to participate if a con ict has to be resolved. Under the assumption that errors occur ....

....a message passing infrastructure. At some point in time, the items must be transmitted over the network. But who should send the item rst in a situation of mutual distrust No matter who begins, there is always the danger of the protocol ending in an unfair situation. In 1980, Even and Yacobi [38] elaborated this idea to formally prove that there is no fair exchange protocol without a trusted third party in these situations. The proof is by contradiction: Assume a protocol exists which achieves strong fairness in the given scenario without the help of a trusted intermediate. The protocol ....
