One Fault is All it Needs: Breaking Higher-Order Masking with Persistent Fault Analysis
fault attacks masking persistent
2019/1/9
Persistent fault analysis (PFA) was proposed at CHES 2018 as a novel fault analysis technique. It was shown to completely defeat standard redundancy based countermeasure against fault analysis. In thi...

2018/11/2
The efficient verification of the security of masked hardware implementations is an important issue that hinders the development and deployment of randomness-efficient masking techniques. At EUROCRYPT...
Secure Multiplication for Bitslice Higher-Order Masking: Optimisation and Comparison
various contexts implementation constraints
2018/4/4
In this paper, we optimize the performances and compare several recent masking schemes in bitslice on 32-bit arm devices, with a focus on multiplication. Our main conclusion is that efficiency (or ran...
The cost of higher-order masking as a countermeasure against side-channel attacks is often considered too high for practical scenarios, as protected implementations become very slow. At Eurocrypt 2017...
