Abstract:
In at least some embodiments, an electronic device comprises a processor and an encryption/decryption (E/D) engine coupled to the processor via a bus. The E/D engine selectively operates in a first mode and a second mode. For the first mode, an E/D engine output is provided to the bus. For the second mode, the E/D engine output is not provided to the bus and is accessible only to the E/D engine.
