Power Leakage Modelling of DES

This weekend, as part of my efforts to advance my learning of power analysis, I attempted to create my own power leakage model of DES and recover a key without referring to previous work. My targets were the ATMega328p board, … Continue reading

Magnetic Correlation Analysis of AES

Over the past week, I have attempted to replicate my power analysis work on AES using a magnetic field / H-Field probe. Unfortunately, there is little literature on the specifics of how to do this, but I was able to … Continue reading

Some thoughts on motivation…

It’s been a while since my last quality shitpost, and it is time I shitposted again. The past year has been a time of growth for me, both in terms of pushing my technical boundaries and in terms of professional … Continue reading

Differential Power Analysis vs AES

This post is a follow-up to my last post regarding correlation power analysis (CPA). A second technique, differential power analysis (DPA), can also be used to analyze power traces to extract information. The specific attack I will illustrate below is … Continue reading

Correlation Power Analysis vs AES

Recently, I spent some time learning about power analysis attacks. This has been an interesting journey with many interesting applications. The theory behind this is simple – that different operations (or – crucially – the same operation with different data) … Continue reading
