Abstract:
A method for integrity checking for a cryptographic engine in a computing system includes monitoring a state of a side channel of the cryptographic engine during operation of the cryptographic engine by a side channel monitor; comparing the state of the side channel to a side channel model of the cryptographic engine to determine whether a mismatch exists between the state of the side channel and the side channel model; and based on a mismatch between the state of the side channel and the model of the side channel, indicating an error in the cryptographic engine.
