Qing Si · 2007
A resolution for anonymity and accountability requirement in E-commerce is proposed which bases on the thought of BRAC and implicates some other skills. There are three main processes: user’s registration, process of trade, and the resolution of complaint. Anonymity of this solution is realized by encryption of the private information of user and the way to save the key in which the key is divided and saved in different places, Accountability is realized by the design of secure protocol and the division of power of the TTP, and the provision of accountability is also given.
