Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Higher-order Hamiltonian generalization evolution equations
高阶 哈密顿 广义演化方程
2023/11/13
In this talk, I will review several classes of higher-order generalizations of the integrable Camassa-Holm equation in the Hamiltonian forms. Then, I talk about some new results for one generalized Ca...
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...

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...

S-box construction Genetic algorithms Higher-order side-channel analysis
2018/1/12
Masking and hiding schemes represent a well-researched and successful option to follow when considering side-channel countermeasures. Still, such measures increase the implementation cost in term of p...
