Description
Power Analysis (and, more generally, Leaked-Emission Analysis) is a technique for guessing the flow of cryptographic algorithms implemented on embedded devices, in particular smart cards. If a single input is used, the process is referred to as a Simple Power Analysis (SPA), and if several different inputs are used together with statistical tools, it is called Differential Power Analysis (DPA). Other attacks include Fault Analysis and Goubin's recent approach.<br/> We review these attacks and some of the contermeasures operating at the algorithmic level devised to thwart them.

Polytopes in the Fiat-Shamir with Aborts Paradigm
Speaker : Hugo Beguinet - ENS Paris / Thales
The Fiat-Shamir with Aborts paradigm (FSwA) uses rejection sampling to remove a secret’s dependency on a given source distribution. Recent results revealed that unlike the uniform distribution in the hypercube, both the continuous Gaussian and the uniform distribution within the hypersphere minimise the rejection rate and the size of the proof of knowledge. However, in practice both these[…]-
