A board for current-based Side Channel Attacks #ReverseEngineering
Two weeks ago we posted on Limpkin’s inductive approach to attacks against secure circuits. Another approach is a current based attack.
Requirements:
– shunt resistor value: reasonably low, between 1R and 10R
– gain: tough one… around 100x, adjustable?
– frequency: let’s aim for 1 to 500MHz
– noise: as low as possible, obviously!
– battery powered
The board is currently being used by several security researchers out there and ICs have already been broken with it!
You can find the source files here and the board is available for sale EU store / US store.
