Abstract
A method and a corresponding apparatus for authenticating data in a digital processing system (DPS) is disclosed, wherein a root/first tier key pair associated with a first tier/root authority may sign data and second tier keys for authorizing data for processing in the DPS. The first tier/root authority may pass entitlements to the authorized second tier key, which may itself authorize third tier keys and pass entitlements to said key.
