Elliptic Curve Cryptography on the WISP UHF RFID Tag
The Wireless Identification and Sensing Platform (WISP) can be used to demonstrate and evaluate new RFID applications. In this paper, the authors present practical results of an implementation of Elliptic Curve Cryptography (ECC) running on the WISP. Their implementation is based on the smallest recommended NIST elliptic curve over prime fields. They meet the low-resource requirements of the platform by various code-size and memory optimizations. Furthermore, they provide a cryptographic framework that allows the realization of different ECC-based protocols on the WISP. They evaluated their implementation results by considering platforms with and without a hardware multiplier.
