Abstract
A trusted data store is provided for use with a trusted element of a trusted operating system on a computing machine. In the trusted data store, a storage medium stores data in a pre-determined arrangement, where the data includes trusted data from the trusted element of the trusted operating system on the computing machine. An access controller writes data to and reads data from the storage medium, and a trust controller is interposed between the computing machine and the access controller. The trust controller allows only the trusted element to perform operations on the trusted data thereof on the storage medium.
