概要

• 論文の詳細を見る

• Many services on ITS (Intelligent transport system) have been proposed, which include the ETC (electronic toll collection) system. In this paper, we first present some assumptions we can assume on ITS. Then we construct a light electronic ticket system which is suitable for payment on ITS. In our system, (1) only two moves are required to use a ticket, (2) the shop can check the validity of the ticket with only a few applying of hash functions. Further, we prove that forgery of a ticket by a user or a shop is detected with almost one probability.
