Secure and efficient tag searching in RFID systems using serverless search protocol

In the coming pervasive society, Radio Frequency Identification(RFID) Tags will be affixed within every product and object including human. This technology is anticipated to be a major technology which will be utilized by several pervasive services where these tags will be used to identify various objects. However, the use of RFID tags may create new threats to the security and privacy of individuals holding RFID tags. Therefore, widespread deployment of RFID systems preserving users’ privacy and data integrity is a major security challenge of the coming year. That is why research related to privacy preserving authentication is growing. And the envision is that: RFID systems can intermingle into human lives if they can offer practical, low cost and secured mechanisms for tag authentication which has been in the midst of researcher’s interest for almost a decade. One extension of RFID authentication is RFID tag searching. Any RFID authentication protocol which provides adequate security and privacy can be used for RFID tag searching. However, when the number of tags within a system will increase, the overall data collection cost will also increase. Therefore, more efficient tag searching method is needed. RFID search protocol can play a major role for tag searching which has not been given much attention so far. But we firmly believe that in near future tag searching will be a significant issue. In this paper we propose a lightweight and serverless RFID tag searching protocol. This protocol can search a particular tag efficiently without server’s intervention. Furthermore they are secured against major security threats.
