So far, efficient algorithmic countermeasures to secure the AES algorithm against (first-order) differential side-channel attacks have been very expensive to implement. In this a...

Abstract. When cryptosystems are being used in real life, hardware and software implementations themselves present a fruitful field for attacks. Side channel attacks exploit infor...
Abstract. We propose a novel approach for quantifying a system's resistance to unknown-message side-channel attacks. The approach is based on a measure of the secret informati...
Attack resistance has been a critical concern for security-related applications. Various side-channel attacks can be launched to retrieve security information such as encryption k...
We demonstrate that masking a block cipher implementation does not sufficiently improve its security against side-channel attacks. Under exactly the same hypotheses as in a Differ...
