Abstract
A circuit includes a first processing unit and a second identical processing unit. A first communication bus passes encrypted data between one of a plurality of functions and one or both of the first and second processing units. A selection circuit determines whether the encrypted bus is coupled to the first processing unit, the second processing unit, or both of the first and second processing units.
