具隱私保護之RFID雙向鑑別機制

Privacy Protection and Mutual Authentication Scheme for RFID Systems

無線射頻辨識 (RFID) 系統已成為製造業、供應鏈管理和零售盤存控制等應用的常見使用工具。不幸地，普遍佈署使用RFID裝置卻可能升高大軍對於隱私與資訊安全的疑慮。本論文利用簡單的互斥或 (XOR) 運算與雜湊 (Hash) 函數，提出一個安全的RFID雙向鑑別機制，此方法不僅具備安全防護及個人隱私保護之特性，而且相當有效率，適用於計算能力弱、記憶體容量小的被動式電子標籤。

Radio frequency identification (RFID) systems are a common and useful tool in manufacturing, supply chain management and retail inventory control, et al. Unfortunately, the universal deployment of RFID devices may raise public concern regarding violation of privacy and information security. In this paper, a secure mutual authentication scheme is proposed which is based on XOR operation assisting and hash function. Our proposed scheme is best suited for RFID systems that enforce user privacy and security protections while they cannot afford high computing powers and memory spaces, for example passive tags.
