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...
Sharing Independence & Relabeling: Efficient Formal Verification of Higher-Order Masking

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

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...

Higher-order masking is a widely used countermeasure to
make software implementations of blockciphers achieve high security levels
against side-channel attacks. Unfortunately, it often comes with a

It is widely accepted that higher-order masking is a sound countermeasure to protect
implementations of block ciphers against side-channel attacks. The main issue while designing such
a countermeasu...
In this paper, we study the problem of automatically verifying higherorder
masking countermeasures. This problem is important in practice (weaknesses
have been discovered in schemes that were though...
Compositional Verification of Higher-Order Masking: Application to a Verifying Masking Compiler

The prevailing approach for building masked algorithms that can resist
higher-order differential power analysis is to develop gadgets, that is, masked
gates used as atomic blocks, that securely impl...
We describe a new algorithm for masking look-up tables of block-ciphers at any order, as a countermeasure against side-channel attacks. Our technique is a generalization of the classical randomized ta...

Masking is a well-known technique used to prevent block cipher implementations from side-channel attacks. Higher-order side channel attacks (e.g. higher-order DPA attack) on widely used block cipher l...
Implementations of cryptographic algorithms are vulnerable to Side Channel Analysis (SCA). To counteract it, masking schemes are usually involved which randomize key-dependent data by the addition of ...
