Hi 👋🏼 Shawn, Many thanks for this very useful review!!! Very useful! We have been thinking about your review comments, tracked at https://github.com/cpignata/eimpact-icmp/issues/27 , and have some follow up questions for you (leaving only the relevant part of the review) 1. For DPA (as in differential power analysis), an attacker would need a “continuous” Current / Power over time curve while the crypto algo is executed. Would the fact that this is getting a single value (not a time series) be a fair high level counter measure? 2. Do these elements typically have DPA protection as in injecting noise? Should we in the results? 3. Could you please share a reference to DPA we could use to add text? And really welcome textual suggestions!!! 😉 Thanks again, Shawn! Carlos.
