Diffusing RFID-Sensor Networks and 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 anticollision protocol existing and applied in the RFID dilemma, sited vulnerabilities and suggested general security solutions.
