SCA Resistance Analysis on FPGA Implementations of Sponge based MAC-PHOTON

N. Nalla Anandakumar

Abstract: PHOTON is a lightweight hash function which was proposed by Guo et al. in CRYPTO 2011. This is used in low-resource ubiquitous computing devices such as RFID tags, wireless sensor nodes, smart cards and mobile devices. PHOTON is built using sponge construction and it provides a new MAC function called MAC-PHOTON. This paper deals with FPGA implementations of MAC-PHOTON and their side-channel attack (SCA) resistance. First, we describe three architectures of the MAC-PHOTON based on the concepts of iterative, folding and unrolling, and we provide their performance results on the Xilinx Virtex-5 FPGAs. Second, we analyse security of the MAC-PHOTON against side-channel attack using a SASEBOGII development board. Finally, we present an analysis of its Threshold Implementation (TI) and discuss its resistance against fi rst-order power analysis attacks.
