Implementation of side channel analysis evaluation boards for cryptographic software of embedded systems

Abstract

Side channel analysis is a powerful cryptanalytic method to reveal secret information of cryptographic devices such as smart cards, USB tokens, OTP devices and secure embedded devices. To prevent side channel attacks we must implement countermeasures against it and evaluate security of these implementations. However, secure embedded devices except smart cards are not easy to evaluate security of them against SCA owing to their complicated components and circumstances. In this paper we designed boards for SCA evaluation of software implementations and tested them with block cipher algorithms.
