Anti-Collision Protocol for RFID-Sensor Network and the Security Threats

To uniquely identify physical objects, Radio Frequency Identification (RFID) systems are used with its limitless possibilities and low cost. RFID is a method of remotely storing and retrieving data using devices called RFID tags. An RFID tag is a small object, such as an adhesive sticker, that can be attached to or incorporated into a product. But with this common scenario involving numerous tags and present in the interrogation zone of a single reader at the same time. RFID is prone to security threat as well, which is the main focus of this paper. In this paper we present an anti-collision protocol existing and applied in the RFID dilemma, sited vulnerabilities and suggested general security solutions.
