| Usually a leaking code runs challenges, one challenge giving a power trace. A challenge is the execution of a code with a specific set of data. This set of data is given in the input of the leakage simulation. For example, one can imagine that the leaking code is a symmetric encryption and one wants to study its power leakage according to the message and the secret key. Then, a challenge is the simulation of the leakage for a specific message and for a specific secret key. | |||
