Interface controller for commodity devices

Abstract

A method, system, and device for using an interface controller to validate and authenticate controller code for a commodity device to be included within a computer system (e.g., a power supply) are provided. In one example, a commodity device controller includes dynamic memory for control software (e.g., control code to control operation of the commodity device) that may be validated (and/or updated) using an interface controller. The interface controller may perform this update/validation at startup (or run-time) to ensure secure control over aspects of the computer device including the commodity device control code. If a security risk is detected it may be mitigated in various ways, including disabling of the commodity device. Control code provided by third-parties (e.g., supplier of commodity device) may be validated and secured using disclosed techniques.
