In this paper we present improvements of the algebraic side-channel analysis of the Advanced Encryption Standard (AES) proposed in [1]. In particular, we optimize the algebraic representation of AES and the algebraic representation of the obtained side-channel information in order to speed up the attack and increase the success rate. We study the performance of our improvements in both known and unknown...
Computer aided design (CAD) tools are fundamental for ensuring a short time-to-market in nowadays chip design. However, while CAD tools support the development of efficient designs, they fail to support the designer with regard to side-channel security. In order to better assist the designer, we propose the AMASIVE (Adaptable Modular Autonomous SIde-Channel Vulnerability Evaluator) framework that...
At the cutting edge of today's security research and development, the SHA-3 competition evaluates a new secure hashing standard in succession to SHA-2. The five remaining candidates of the SHA-3 competition are BLAKE, Grøstl, JH, Keccak, and Skein. While the main focus was on the algorithmic security of the candidates, a side channel analysis has only been performed for BLAKE and Grøstl [1]. In order...
