Abstract
A secure reconfigurable operating mode system includes a hardware device having multiple operating modes and an operating mode selector that is coupled to the hardware device. The operating mode selector has a virtual fusing register that selects an operating mode for the hardware device and a security processor that enables a secure virtual fusing based on documented security files authorizing selection of the operating mode. A method of secure hardware device operating mode reconfiguration is also provided.
