A Novel ID-based Electronic Cash System from Pairings
Jue-Sam Chou, Yalin Chen, Ming-Hsun Cho, and Hung-Min Sun
Abstract
Recently, Chen et al. and Juang et al. each proposed one and two e-cash payment systems respectively. They claimed that their schemes are secure. However, in this paper, we will present the shortcomings of their schemes and then propose a novel one from pairings. After security analysis and comparison, we conclude that our scheme not only is more secure but also possesses more functions that a secure electronic cash system should encompass than all of the proposed protocols.
