RMAC -- A Lightweight Authentication Protocol for Highly Constrained IoT Devices

Ahmad Khoureich Ka

Abstract

Nowadays, RFID systems have earned an important place in our everyday lives. Its adoption is growing in areas where data security or privacy or both must be guaranteed. Since the RFID tag can be cloned, it is necessary to develop appropriate security solutions for these systems. Fortunately, many papers have proposed solutions for encryption or authentication. But it turns out that sometimes the proposal has security flaw or is too complicated for the RFID tag (which has very limited computing resources). In this paper we introduce a new authentication protocol using a new approach. Our proposal named R-MAC is well suited for RFID tags since it uses simple and lightweight constructions. R-MAC is at least as secure as the Mirror-Mac protocol introduced by Petros Mol et al.
