[PDF] Top 20 Higher-Order Threshold Implementations

... To calibrate our threshold value we apply the test methodology to two groups of 10 000 measurements each for which we know that the null hypothesis is true. For the first group of measurements we switch off the ... See full document

... In general, checking that an implementation is protected against side-channel attacks is a complex and error-prone process (see [29] for an overview). As a re- sult, countermeasures relying on a more established theory ... See full document

... Abstract. Side-channel attacks have proven many hardware implemen- tations of cryptographic algorithms to be vulnerable. A recently proposed masking method, based on secret sharing and multi-party computation methods, ... See full document

... To defeat white-box implementations, Bos et al. proposed in [4] the Differ- ential Computational Analysis (DCA). This attack is the software adaptation of the well-known Differential Power Analysis (DPA) [10]. ... See full document
