| Abstract: | Electronic cash scheme has been studied in manyyears. The one of important options is traceability. In this paperwe develop a new protocol for untraceable electronic cash. Thesecurity of the system is based on DLA (Discrete Logarithm As-sumption) and the cut- and- choose methodology. |
