Consolidating Masking Schemes
In this paper we investigate relations between several masking schemes. We show that the Ishai–Sahai–Wagner private circuits construction is closely related to Threshold Implementations and the Trichina gate. ...

Selecting Time Samples for Multivariate DPA Attacks
Masking on the algorithm level, i.e. concealing all sensitive intermediate values with random data, is a popular countermeasure against DPA attacks. A properly implemented masking scheme forces an attacker to ...

Theory and Practice of a Leakage Resilient Masking Scheme
A recent trend in cryptography is to formally prove the leakage resilience of cryptographic implementations – that is, one formally shows that a scheme remains provably secure even in the presence of side channel...

To Infinity and Beyond: Combined Attack on ECC Using Points of Low Order
We present a novel combined attack against ECC implementations that exploits specially crafted, but valid input points. The core idea is that after fault injection, these points turn into points of very low or...

The World Is Not Enough: Another Look on Second-Order DPA
In a recent work, Mangard et al. showed that under certain assumptions, the (so-called) standard univariate side-channel attacks using a distance-of-means test, correlation analysis and Gaussian templates are ess...
