HI, actually you can do that with Avrora: * Use the printf Future to log the start and stop of your encryption * After that you can compute the energy consumption with the help of the elogs, you just have to compute U * I * t. The overhead for printing the printf statement is quite low ~2-3 cycles, so the overall consumption will be ver close to the real values.
