“Threshold Implementations - provably secure countermeasure against physical attacks“


Copyright: CASA, Nikova

Abstract: With the increase in portable devices performing cryptographic computations, physical attacks are becoming easy to execute. One of the most common physical attacks is Side-Channel Analysis (SCA), extremely dangerous due to its non-invasive nature. Threshold Implementations (TI) was proposed as the first countermeasure to provide provable security in masked hardware implementations. 

In this lecture we will first introduce the method and give examples of HW implementations using Threshold Implementations. Then we will present the most recent developments in the theory and practice of Threshold Implementations and will demonstrate Tis providing various trade-offs and achieving efficiency and security of HW implementations.
