設計與實作以RFID為基礎的防偽系統
– 以Mifare 1 S50、ISO 15693、Class 1 Gen2實作

RFID近年來主要應用領域為身分辨識、大眾運輸票據、庫存盤點、物流供應鏈管理等，隨著RFID技術的不斷進步，如何利用RFID達到創新應用來改善人們的生活，也一直是此一領域主要的研究課題。RFID的技術逐漸成熟，製造成本也隨之降低，因此業界有越來越多的廠商選擇使用RFID卡片附貼在產品上，用做產品的物流、庫存管理與盤點。 RFID卡片的記憶體區塊除了儲存卡片唯一的識別碼外，還允許使用者能夠將資訊寫入卡片，若只以RFID做為產品的物件辨識，並沒有發揮RFID的所有效能。隨著產品偽造的日益猖獗，使用者從外觀上很難去辨識真品與偽造品的差別，考慮到未來越來越多產品將附貼上RFID卡片，我們希望能夠利用RFID的記憶體區塊，來達到產品的防偽應用。近年來有不少的理論研究希望能利用RFID防偽，雖然有的研究已經將理論上的防偽機制實作出實體卡片，但因不是利用市面上常見的晶片來設計，且皆為小量製作，故成本昂貴。本論文分別以市面上常見的三種RFID卡片規格：Mifare 1 S50、ISO 15693、EPC Class 1 Gen 2，探討三種規格RFID的不同特性，在不改變其卡片晶片設計情況下，進行防偽應用的設計，並根據設計實作出RFID防偽應用系統。最後我們提高防偽需求的標準，希望能達到不可追蹤性，我們提出一個不以現有RFID規格做規劃的RFID防偽機制。

RFID has been successfully applied in identity recognition, public transportation tickets, inventory control, logistics and supply chain management, etc. With RFID technology continues to progress, how to achieve innovative application of RFID to improve people's lives has been one major research topic in this area. With the costs of RFID continues to drop, more and more products being labeled with RFID to facilitate logistics and inventory management. RFID card not only stores a unique number for identification, but also allows users to write information into the card. Taking RFID only for product identification does not bring it into full play. As the problem of product counterfeiting become more and more serious, RFIDs are deemed to be promising solutions to product anti-counterfeiting. There are some publications of anti-counterfeiting using RFIDs. However, these solutions all re-design RFID chips instead of using commercial available RFIDs, and it is highly costly to design and produce new chips. In this thesis, we based on three commercial available RFID chips - Mifare 1 S50, ISO 15693, and EPC Class 1 Gen 2, design and implement RFID-based anti-counterfeiting systems. The three RFID chips have different memory storage, security functions, and costs, and they fit different sectors of products on the market. Therefore, the three RFID-based counterfeiting systems are designed to fit different market sectors. To further purchasing an ideal RFID-based counterfeiting system with un-tracable function, we propose a new RFID-based counterfeiting system using new RFID chip.
