Abstract
A multi-tiered static chain of trust is established in a computer system which utilizes a first authentication program stored on a first memory device to authentic data stored on a second memory device. If the data stored on the second memory device is authenticated, then a second authentication program stored on the second memory device authenticates data stored on a third memory device. If the data on the third memory device is authenticated the computer system is allowed to utilize the data stored on the third memory device. The data stored on the third memory device is indirectly authenticated while the data is being used by authenticating the data stored on the first memory device.
