A protocol for untraceable electronic cash

Wang, Hua and Zhang, Yanchun (2000) A protocol for untraceable electronic cash. In: 1st Web-Age Information Management International Conference (WAIM 2000), 21-23 Jun 2000, Shanghai, China.


In this paper we develop a new protocol for untraceable electronic cash, in which the bank involvement in the payment transaction between a user and a receiver is eliminated. The user withdraws electronic 'coins' from the bank and uses them to pay to a receiver. The receiver subsequently deposits the coins back to the bank. In the process the user remains anonymous, unless she spends a single coin more than once (double spend). The security of the system is based on DLA (Discrete Logarithm Assumption) and the cut-and-choose methodology.
