Research on the Fair Exchange Protocol Using Hash Function Chains
利用Hash函数链的公平交易协议研究*

Based on the in-depth research on the existing fair exchange protocol models,a new fair exchange protocol using Hash function chains is proposed.It utilizes the one-way property of Hash function to realize the unit-by-unit release of secrets,and uses the Hash function chains as paying warrant.The protocol has simple structure,higher security,less traffic and greater processing efficiency.
