Security analysis of RFID tags

Abstract

Usage of Radio Frequency Identication is winning ground everywhere. Advantages of contactless communication compared to chips with contact are transaction speed, durability and ease to use. A major disadvantage is that messages can be intercepted from a distance by a malicious user. Eavesdropping of unsecured transmissions can be a serious security risc. This research describes a way to intercept this information. Furthermore, it shows the vulnerabilities in dierent major RFID systems and demonstrates how to exploit them.
