摘要
提出了一种保护隐私的公平可追踪电子交易方案。方案采用改进了的一次性盲公钥和代理签名技术,实现了消费者消费信息的隐私性和对欺诈者的可追踪性;方案中对订单信息的公平性签名,使得交易双方要么都能获得对方对于订单的签名,要么都不能,可有效防止抵赖,提升了交易的公平性。分析表明方案是安全、高效、完整的,其隐私保护和公平交易的特性将有利于电子交易的进一步发展。
A fair traceable privacy-preserving electronic transaction scheme is proposed. Based on one-offblind public key and proxy signature, the privacy of consuming information is reserved and the cheating behavior can be traced; the fair signature of the subscription can make both or neither of the two trading parties get the signature from the other side, upon that it can avoid denying effectively, and the fairness of the transaction is promoted. Analysis shows its security, efficiency and integrality are perfect, its trait of privacy-preserving and fair exchange can avail the development of the electronic transaction.
