A vector-space-based lightweight RFID authentication protocol

Radio frequency identification (RFID) is becoming one of the best optimistic technology in the area of ubiquitous computing that plays the most crucial role in object identification as a ubiquitous infrastructure. Indeed, an important role of RFID technology is to provide wireless communication between the RFID tags and readers without line-of-sight (LoS) readability. The tags store the sensitive information of an object or thing in RFID systems. The reader reads and writes data, while the backend server stores the information sent by the readers through radio frequency signals. Moreover, the reader collects data from the distinct tags and broadcasts them, and then sends it to the server for further processing. However, security and privacy is a key concern in RFID systems, where an adversary may perform several types of security attacks. To overcome such issues, we have proposed a novel vector-space-based lightweight RFID authentication protocol which integrates the concept of vector space, basis, and linear mapping in this paper that achieves secure authentication. The security analysis has been done that demonstrates the proposed protocol provides resistance to various known attacks. The performance analysis shows the less computation cost associated with the tags, less storage, and communication overhead as well. The proposed protocol provides higher security with lesser cost and shows suitability for low-cost RFID systems.
