Abstract
An integrated circuit includes functional circuitry such as a processing core, memory interfaces, cryptographic circuitry, etc. The integrated circuit also includes protection circuitry to protect the functional circuitry of the integrated circuit against attacks by hidden channels. The protection circuitry, for each of a series of successive periods of time, selects a configuration of the functional circuitry from a set of configurations of the functional circuitry, sets a duration of the period of time, and applies the selected configuration of the functional circuitry for the set duration of the period of time.
