近年來各國由於車輛快速成長,高速公路的容量早已不敷使用,拓寬車道或新闢道路的做法無法有效減緩路況惡化的速度。有鑑於此,如何利用先進的通訊及資訊技術,達到在交通上做到更有效率的管理目的,已經成為世界各國改善交通的重要方向。因此,在交通運輸上如何提高運輸的效率已成為一項重要的議題。
2003年Matsuo與Ogata提出一套適用於ITS(Intelligent Transport System)上的ETC(Electronic Toll Collection)電子收費系統機制,其主要目的是解決過去的付款方法中因繁複的通訊步驟與冗長驗證時間所帶來的效率不佳的問題。
然而, 我們發現Matsuo與Ogata的方法因缺少了票券申請者對發行者認證的動作,導致票券申請者無法驗證所取得的票券因子是否有效,以致於票券申請者可能會面臨拿到偽造票券的風險。
此外,於票券回收階段,票券的發行者也沒有作對商家認證的動作,導致攻擊者可以在票券使用階段時先攔截電子票券,並於票券回收階段時假冒商家可先向票券發行者成功取得電子票券之款項。
因此,本論文除了指出Matsuo與Ogata的方法中有被惡意者攻擊的風險外,更進一步提出了我們如何改進的方法,我們不但保留了他們原先提出電子票券方法的優點,也同時避免了我們所指出的兩項安全疑慮,使電子票券更安全的被使用在ITS上。
The amount of vehicles has grown up rapidly in many countries in recent years. The capacity of freeways is very limited. Broadening driveways or building new roads haven’t effectively prevented the traffic from worsening. How to use advanced technology to make the efficiency of communications and transportation has become an important policy for many countries. Especially, how to use the Electronic Toll Collection, ETC to enhance the transportation efficiency on traffic has become an essential issue.
In 2003, Matsuo and Ogata proposed a scheme of ETC which was suitable for Intelligent Transport System, ITS. The purpose was to solve the inefficiency caused by complicated communication steps and long verification of payments in the past.
But, we found the security flaws in their scheme. That is the ticket user can not verify if the ticket seed is valid or not. It was occurred by this method without the authentication from user to issuer. It caused the risk of user to get the forge ticket seed.
Specially, at the period when refluxing the tickets, the ticket issuer do not have to verification identification on the shops, which causes attackers could to intercept the tickets, and acted be the legal shops to get the money successfully.
Therefore, in this paper we point out the risk to be attack on Matsuo and Ogata’s method, and we also proposed how an improvement method. We not only to keep the original advantages of Matsuo and Ogata’s method but also avoid those two security concerns we brought up to strengthen and improve the security of the use of electronic ticket on ITS.
