Cryptographic devices are vulnerable to Differential Power Attack (DPA) in embedded systems. Masking methods are popularly used to defend against DPA by masking all intermediate data with random values. However, masking schemes on algorithm level are vulnerable to Higher-Order DPA (HODPA), while on gate level glitch attack is the biggest threaten attack. In this paper, we proposed a secret sharing based countermeasure for AES S-box, which can defend against both HODPA and glitch attack. The experimental results show that our proposed design takes up less hardware resources and achieves faster speed compared with the existing methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
