Physical side-channel attacks on cryptographic systems
We survey a number of attacks on cryptographic systems which depend on measuring physical characteristics of such systems whilst a given cryptographic operation is carried out. Such measurements could include the time needed to perform certain operations, the power consumed or any electromagnetic radiation produced. As such the physical measurement is producing a side-channel for the cryptograp...
متن کاملPertinent Side Channel Attacks on Elliptic Curve Cryptographic Systems
Elliptic curve cryptosystems have become the most trusted, secure systems in widespread use today. However, the recent advent of utilizing side channel information poses an immediate and powerful threat to systems which are not prepared for this exact type of attack. Side channel analysis (SCA) attacks use some measured quantities outside the scope of the actual cryptographic algorithm, in addi...
متن کاملSide channel attacks on cryptographic devices as a classification problem
In this contribution we examine three data reduction techniques in the context of Template Attacks. The Template Attack is a powerful two-step side channel attack which models an almost omnipotent adversary in the profiling step, but restricts him to a single observation in the classification step. The profiling step requires data reduction due to computational complexity and vast amounts of da...
متن کاملSide Channel Attacks on Implementations of Curve-Based Cryptographic Primitives
The present survey deals with the recent research in side channel analysis and related attacks on implementations of cryptographic primitives. The focus is on software contermeasures for primitives built around algebraic groups. Many countermeasures are described, together with their extent of applicability, and their weaknesses. Some suggestions are made, conclusion are drawn, some directions ...
متن کاملSpectrum Analysis of Cryptographic Modules to Counteract Side-Channel Attacks
This paper proposes a spectrum analysis method to identify the frequency band that can be used to perform power analysis attacks against cryptographic modules. The proposed method conducts Differential Power Analysis (DPA) in the frequency domain instead of the time domain. The result is then used to identify the frequency bands containing information leakage. The performance of the proposed me...
