dc.description.abstractRFID(無線射頻辨識)是一種利用無線射頻傳送識別資料的技術,提供小型且非接觸式通訊,應用層面相當廣泛,被視為未來生活上的基礎設建設。但是,RFID Tag硬體在先天上的限制,引發許多威脅到安全性的問題產生,如:隱私問題、Tag 竊聽、追蹤或複製等攻擊。針對這些相關安全議題,許多的相關研究被提出來,Blocker Tag便是其中之一。 Blocker tag是對於隱私權保護的一個解決方案,是一種類似干擾訊號的演算法,利用這個演算法來保護tag不會被讀取。但是,一旦這個方案被人惡意的濫用,人們可以在商店中帶走商品並巧妙的避過結帳掃描等,可能會造成商業或作業損失的缺失,而如何去偵測出是否有存在Blocker tag,即是一種需要解決的問題。 為了解決這個問題,本篇論文設計出SLN-algorithm來偵測存在的Blocker tag,經由模擬實驗結果,證明不僅能有效的偵測Blocker Tag的存在,並且與[1]比較後偵測率和效能都勝出。zh_TW
dc.description.abstractRadio Frequency Identification (RFID) is a sensor network technology to automate identification. RFID systems had been applied to many fields and have been considered as a key infrastructure for the ubiquitous society in the future. However, due to the inherent drawbacks, RFID causes various security threats like privacy problems, tag wiretapping, tracking or cloning, etc. To address these issues, lots of solutions had been proposed. The Blocker Tag is one of these. Blocker tag is a solution for privacy protection. It uses a kind of algorithm which is similar to using jamming signal. However, if this method is used in malicious way, the inventory process of the RFID reader might be stopped, and people in department store may carry some merchandise out without accounting. Find out a way to detect the Blocker Tag could be an important issue on RFID. To resolve this problem, we proposed a scheme“SLN-algorithm” to detect the existence of Blocker tags. In our experiments, the results have demonstrated that our detection mechanism is more effective than the mechanism proposed in [1] on detecting Blocker Tag.en_US
