Abstract:
A method for processing content stored on a component is disclosed. A first partition of a first memory is encrypted with a first encryption key and a second partition of the first memory is encrypted with a second encryption key. The second encryption key is different from the first encryption key. The first encryption key is stored in a storage register of the component and the second encryption key is stored in a first location of a non-volatile memory. A memory address of the first location is stored in the first partition of the first memory.
