Side-channel Attack user reference architecture board SAKURA-W for security evaluation of IC card

Abstract

Side-channel Attack User Reference Architecture board SAKURA-W was developed to evaluate the physical security of IC cards equipped with cryptographic function. SAKURA-W works as a daughter board of SAKURA-G and uses hardware resources of SAKURA-G such as a controller FPGA and a USB interface. In this paper, we describe the basic functionality of SAKURA-W, and show its advantages over SASEBO-W, which is a conventional IC card evaluation board, through side-channel attack experiments using AES software on an 8-bit processor IC card ATMega163.
