Abstract: | This paper adopts a holistic approach to Radio Frequency Identification (RFID) security that considers security and privacy under resource constraints concurrently. In this context, a practical realisation of a secure passive (battery-less) RFID tag is presented. The tag consists of an off the shelf front end combined with a bespoke 0.18 μm Application Specific Integrated Circuit (ASIC) assembled as a -sized prototype. The ASIC integrates the authors’ ultra low power novel Advanced Encryption Standard (AES) design together with a novel random number generator and a novel protocol, which provides both security and privacy. The analysis presented shows a security of 64-bits against many attack methods. Both modelled and measured power results are presented. The measured average core power consumed during continuous normal operation is 1.36 μW. |
