Abstract: “Ultra wide band (UWB) leads promising technology for next generation communication especially for high data rate & short range application. Existing secure RFID tags rely on digital cryptographic primitives in the form of hashes & blocks ciphers which leads to large system latencies. Existing RFID systems can easily be eavesdropped or jammed. To overcome the above problem we propose a new approach for secure passive RFIDs based on UWB communication. In architecture of UWB the time hopped pulse position modulation (TH-PPM), in which the hopping sequence is known only to the reader & the tag. Eavesdropping of the communication is extremely difficult by adopting the hopping sequence as a secret parameter, thus by using UWB modulation technique we can avoid digital cryptography”
