摘　　要：针对目前电子商务微支付方案中所存在的密钥托管、匿名性以及公平性等问题,提出一种新型的电子商务微支付方案。在认证与密钥协商子协议中,通过盲化技术和双线性运算,在没有第三方参与的情况下,实现用户和商家之间的相互认证,并得到一个共享的密钥,可以有效地提供匿名性。在支付子协议中,在双Pay Word链的基础上,结合同时生效的数字签名,实现了交易的完全公平性。A new e-commerce micro payment scheme is proposed to solve the problems existing in the current e-commerce micro payment scheme, such as key escrow, anonymity and fairness, etc. In the authentication and key agreement sub-pro- tocol, through the blind technology and bilinear operations, it can realize mutual authentication between user and merchant without the participation of the third party, and get a shared key. It also can provide some anonymity. In the payment sub- protocol, combined with concurrent signature, the scheme can realize absolute fairness based on double Pay Word chains.
