'N-variant' microchips could protect intellectual property, enable new services

Rice University computer engineers have created a way to design integrated circuits that can contain many multiple selves. The chips can assume one identify or a subset of identities at a time, depending on the user's needs. New research shows that multiple "personalities" in an integrated circuit can be even a more powerful security mechanism that can be used for a variety of digital rights management tasks as well as for circuit optimization and customization without sacrificing the related power, delay and area metrics.
