具加密與認證機制之主動式RFID系統

Active RFID System with Cryptography and Authentication Mechanisms

指導教授 : 李仁貴

摘要


目前,隨著無線射頻 (RFID)技術的不斷發展與RFID相關的應用大量湧現。在實際使用過程中,為了因應潛在的安全問題以及降低對使用客戶隱私權的保護,RFID的安全性問題也開始凸顯。用加密的方法來解決RFID安全性議題是一種辦法。 本系統結合公開金鑰演算法加密技術、嵌入式計算與無線通訊技術,搭配自行研發之主動RFID系統,研製一具有加密機制及驗證能力的主動式RFID系統。經過認證的RFID Tag間歇性地發送密文(cipher text)資料,RFID Reader接收Tag密文資料並以多點跳躍接力的方式傳至後端平台,後端平台鑰匙中心進一步進行資料比對,完成安全認證流程。其中,系統採用公開金鑰演算法TTS (Tame Transformation Signature),其具有高安全性、高速生鑰、有效運算能力等特性,故可使整個主動式RFID系統更能有效進行資料加密與驗證。 本文成功實現三大研究重點,一為自製研發主動式RFID系統,並包含Tag及Reader兩大裝置,二為利用公開金鑰演算法實踐於主動式RFID完成整個認證系統,另一為在RFID 系統上採用多點跳躍的機制,使無線傳輸距離範圍得以延長,並獲得有效利用。這三大議題亦為此篇論文的主要貢獻。

Radio frequency identification (RFID) systems are used a large number of applications. Regarding security problems and consumer’s privacy issues become significant challenge in these systems. Therefore, to solve the RFID security problem is essential topic today. In this thesis, we integrate public key encryption, embedded computation, and wireless communication technologies into the active RFID system that we proposed system with cryptography and authentication mechanisms. In proposed active RFID system, secured RFID Tag transmits cipher text, authenticated by key center, to the Reader by clustering. And then, Readers transmit the data the back-end platform by means of multi-hop relaying for authentication. Additionally, the digital signature scheme–TTS (Tame Transformation Signatures) is used in the proposed system to protect the plain text. The TTS algorithm is the families of asymmetric public key systems. Some properties of TTS have superior of security, fast key generation, complex algorithm, and low signature delay those can encrypt data and authenticate more effectively in active RFID system. Finally, we have contributed three items in this thesis. One is fully design and implement an active RFID system includes active Tags and Readers. Second is successful to implement proposed active RFID system with cryptography and authentication mechanisms. The last is to adopt multi-hop relay extend distance between Readers.
