Abstract

A range test scheme proposed by Peng et al. presents a new method to test whether a secret integer is in a certain interval range. However, several limitations affect its applicability and make its suggested applications difficult. In this paper, the range test technique is practicalized to overcome the limitations. The practicalized range test technique is employed to design a secure e-auction scheme, which has advantages over the existing secure e-auction schemes and demonstrates practicality of the optimised range test technique.
