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...
Abstract. In the recent years, DPA attacks have been widely investigated. In particular, 2-nd order DPA have been improved and successfully applied to break many masked implementat...
In the recent years, Higher-order Side Channel attacks have been widely investigated. In particular, 2nd-order DPA have been improved and successfully applied to break several mask...
Differential Power Analysis (DPA) is a powerful side channel key recovery attack that efficiently breaks block ciphers implementations. In software, two main techniques are usually...
Most side-channel attacks that have been published in the open literature assume known- or chosen-message adversarial scenarios. In this paper, we analyze the increase of the attac...
