Abstract
A system and associated method for controlling access to features of a device are provided. The system includes a feature access component that maintains an access control register configured to store an access control parameter indicating whether a user has access to a feature of the device. Responsive to receiving a request to modify the access control register to enable or disable access to the feature, an access authentication parameter is set to an authentication key of the request and an access parameter is set to a value of the request (e.g., 1 “Enable”). The access authentication parameter and access parameter are evaluated utilizing an authentication algorithm. Responsive to successfully authenticating the request, the access control register is modified based upon the value of the access parameter, such as to indicate that the user is now authorized to read and/or modify a parameter and/or invoke a service to execute.
