Non-profiled Mask Recovery: the impact of Independent Component Analysis
Side Channel Analysis Masking Independent Component Analysis
2018/11/13
As one of the most prevalent SCA countermeasures, masking schemes are designed to defeat a broad range of side channel attacks. An attack vector that is suitable for low-order masking schemes is to tr...

Refreshing algorithms are a critical ingredient for secure masking. They are instrumental in enabling sound composability properties for complex circuits, and their randomness requirements dominate th...
Exact Security Analysis of Hash-then-Mask Type Probabilistic MAC Constructions
MAC secret-key cryptography
2016/12/8
Probabilistic MAC (message authentication code) is an alternative choice for a stateful MAC where maintaining internal state may be difficult or unsafe. Usually tag of a probabilistic MAC consists of ...
Masking is a widely used countermeasure to protect block
cipher implementations against side-channel attacks. The principle is to
split every sensitive intermediate variable occurring in the computa...
