Second-order analyses have shown a great interest to defeat first level of masking protections. Their practical realization remains tedious in a lot of cases. This is partly due to the difficulties of...
The LLL algorithm (from Lenstra, Lenstra and Lovász) and its generalization BKZ (from Schnorr and Euchner) are widely used in cryptanalysis, especially for lattice-based cryptography. Precisely unders...
Time-Frequency Analysis for Second-Order Attacks
Bi-variate attacks zero-offset 2O-CPA discrete Hartley transform
2016/12/10
Second-order side-channel attacks are used to break first-order masking protections. A practical reason which often limits the efficiency of second-order attacks is the temporal localisation of the le...
A Practical Second-Order Fault Attack against a Real-World Pairing Implementation
Pairing-Based Cryptography Fault Attacks eta Pairing

Several fault attacks against pairing-based cryptography have been described theoretically in recent years.
Interestingly, none of these has been practically evaluated. We accomplish this task and pr...
Arithmetic Addition over Boolean Masking - Towards First- and Second-Order Resistance in Hardware

A common countermeasure to thwart side-channel analysis
attacks is algorithmic masking. For this, algorithms that mix Boolean
and arithmetic operations need to either apply two different masking

this paper we find the lower bound of second-order nonlinearity of Boolean function $f_{\lambda}(x) = Tr_{1}^{n}(\lambda x^{p})$ with $p = 2^{2r} + 2^{r} + 1$, $\lambda \in \mathbb{F}_{2^{r}}^{*}$ and...

In this paper we find a lower bound of the second-order nonlinearities of Boolean bent functions of the form $f(x) = Tr_{1}^{n}(\alpha_{1}x^{d_{1}} + \alpha_{2}x^{d_{2}})$,where $d_1$ and $d_2$ are Ni...

The second-order nonlinearity, and the best quadratic approximations, of Boolean functions are studied in this paper. We prove that cubic functions within the Maiorana-McFarland class achieve very hig...

2010/12/22
Second Order Differential Power Analysis (2ODPA) is a powerful side channel attack that allows an attacker to bypass the widely used masking countermeasure. To thwart 2ODPA, higher order masking may b...
