Abstract:	本研究問題是探討現行之RFID認證機制，經由文獻之探討及安全性之分析，進而發展出一個更完善的認證機制。本研究所提之RFID認證機制是透過文獻之探討，發現這些機制中仍存有安全漏洞，因此本研究使用單向耐碰撞雜湊函數與互斥或運算，確保標籤資料之保密性，加上應用錯誤更正碼(Error-Correcting Codes)的匿名性及不可追蹤性，重新設計了一個安全的RFID認證機制，來改良在文獻探討中所發現之安全漏洞。結果發現，本研究所提之RFID認證機制，達到了RFID系統之保密性、不可追蹤性、匿名性及溝通時的完整正確性，在RFID系統中之標籤數量上無上限，在後端伺服器(server)方面也不需進行大量的搜尋資料庫而耗費大量的成本，且若攻擊者破壞標籤(tag)，取得存放於標籤內之資訊並進行分析，但仍無法去影響其他標籤之正常運作。 This research reviews some current RFID authentication schemes, discovers their security flaws, and develops a better RFID authentication scheme based on the discovery. A new low-cost privacy preserving RFID authentication scheme is proposed, using one-way hash function to protect confidentiality and the error-correction code’s characteristic of anonymity and untraceability to measure up the security of RFID system. Security analysis, efficiency evaluation, and comparison with other schemes are also given. The results show that the proposed RFID authentication scheme achieves not only confidentiality, untraceability, and anonymity but also the applicability to large quantity of tags. Besides, searching the whole database in the server is not required. In addition, breaking one tag will not affect the secure operation of the others. This is the major contribution of this research.
