Xiaoxin Ye, Zhenfu Cao, Xiaohui Liang · Jisuanji gongcheng · 2009
The paper proposes a new fair document exchange protocol.In such a fair exchange scenario,each party owns a valuable secret message and they want to exchange their secrets in a fairness way so that at the end of the transaction,either both of them get the other’s secret or neither of them gets the other’s secret.Compared with previous fair exchange protocols,the protocol holds confidentiality,that is,except the two participating party,no one even the Trusted Third Party(TTP) can get exchanged items.
