Abstract

According to one embodiment, an integrated electronic circuit has a switching network configured to receive binary control states, one or more secret-carrying gates, wherein each secret-carrying gate represents Boolean secrets and is configured to receive binary input states and to output one or more Boolean secrets according to a state sequence of the binary input states, and one or more flip-flops configured to store binary output states output by the switching network and to supply binary input states to the one or more secret-carrying gates based on the stored binary output states. The switching network generates the binary output states by combining the binary control states and Boolean secrets output by the one or more secret-carrying gates. The integrated electronic circuit outputs Boolean secrets from the one or more secret-carrying gates and/or the binary output states from the switching network to another integrated electronic circuit.
