How Differential Power Analysis (DPA) works? An explanation of the first paper from Kocher et al (1998)

posted January 2015

I wanted to get into educational videos and this is my first big try (of 13minutes). I made some quick animations in Flash and some slides and I recorded it. I didn't want to spend too much time on it. It doesn't feel that clear, my English kinda got stuck sometimes and my animations were... crappy, let's say that :D but it's a first try, I will release other videos and improve on the way hopefully :) (I really need to get more pedagogical). So I hope this will at least help some of my fellow students (or people interested in the subject) in understanding Differential Power Analysis

Note: I made a mistake at the start of the video, DPA is non-invasive (source)

Well done! You've reached the end of my post. Now you can leave me a comment :)


C'est cool que tu te sois chauffé pour ça !
