الوصف: | Since the invention of blind signatures in 1982 by David Chaum, there have been many proposals to realize anonymous electronic cash using this mechanism. Although these systems offer high privacy to the users, they have the disadvantage that the anonymity might be misused by criminals in order to commit a perfect crime (without being physically present, and thus with the assurance of not being caught). The recent research focuses therefore on the realization of fair electronic cash systems where the anonymity of the coins is revocable by a trustee in the case of fraudulent users. In this paper, we describe the main characteristics of these systems and give a comparison of existing ones. The analysis allows us to propose a new efficient fair cash system which offers scalable security with respect to its efficiency. Our system is the first that prevents extortion attacks, like blackmailing or the use of blindfolding protocols under off-line payments and with the involvement of the truste. |
