Zhengquan Li · Journal of Yangzhou University · 2008
Based on the secret sharing technique,this paper proposes a multi-party fair exchange protocol.The protocol uses an online trusted third party(TTP) in order to help the participants to realize fair exchange.The advantage of a protocol implemented with an online TTP is that the TTP is semi-trusted.Fairness of the proposed protocol is proved in this paper.
