Explanation

A Simple Power Analysis (SPA) attack against a device directly observes the consumption of power by the device. SPA is a type of side channel attack that exploits the variations in the power consumption of a device, such as a smart card or a cryptographic module, to infer information about the operations or data processed by the device. SPA can reveal the type, length, or sequence of instructions executed by the device, or the value of the secret key or data used by
