Optimistic fair exchange protocol suitable for P2P network
|
Abstract:
According to the characteristics of P2P network, an optimistic fair exchange protocol was proposed, which was suitable for P2P network. Trusted Third Party (TTP) in traditional fair exchange protocols was substituted by a distributed temporary node set in this protocol, which effectively reduced the dependency on the honesty of TTP and the reliability of communication channel. The protocol can provide full fairness and security guarantee under the condition that at least 2/3 nodes in the temporary node set are honest.
