近年來無線射頻辨識系統(Radio Frequency Identification;RFID)的發展趨勢廣受矚目,其應用層面已逐漸被廣泛地用於各行各業中。根據國內外的相關研究顯示,RFID以不同的面貌型態融入人們的日常生活中,舉凡悠遊卡、門禁…等,儼然已與我們生活型態成密不可分關係。倘若能善用RFID的優點特性,不斷地研發創新,完備的規劃並完善建置,俾能使其提高作業效率及降低人力成本,亦將提供對於相關產業及生活水準其高效率之平台。 然而一項系統技術即使再如何地完美,若無法普及民眾的生活,無法使民眾隨時便於使用,那麼仍然也只是個願景罷了。因此本研究望藉由攜帶RFID卡片能取代攜帶一堆金錢或被攜帶的金錢所限制之麻煩,以及防止被惡意攻擊之安全問題,採用RFID的安全性MiFare。透過Mifare能針對每一區塊做驗證,以及設定Key A、Key B之存取條件以控制讀寫功能的安全特性,將其應用於校園情境中的消費學校餐廳等消費場所系統之設計,盡可能地發揮無線射頻之優點,以利開發校園系統,盼能透過RFID在校園內普及化,以充分利用無線射頻系統的實用性。
Radio Frequency Identification(RFID)now is a popular technology, and it has been widely deployed in many daily applications like access control, inventory control, MRT ticket, supply chain management, etc. Once we take the advantages of RFID technology, keep researching and innovating as well as plan and establish completely, then we can enhance operating efficiency and reduce the labor cost, and also provide high-efficiency platforms for related industries and living standard. This thesis focuses on designing and implementing secure RFID campus applications. We choose Mifare standard card because it provides multi-sectors and each sector has its own access keys. It facilitates designers to design multi-applications on one card. In this study, we design an e-cash system which covers the applications in seven-eleven convenient store, restaurant and ticket selling service. Through prototyping, we hope to build up a reference model for future campus deployment.
