Power analysis is a technique to probe the inner workings of an integrated circuit by measuring changes in the supply current. Tim writes:
Whenever a logic gate switches, it will cause a tiny current spike that can be measured externally. By inspecting the temporal variation, especially in reaction to an external signal, it is often possible to deduce information about the construction of the IC.
