MULTI-TIERED STATIC CHAIN OF TRUST

摘要

Atty. Dkt. No.: 100598-0751 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. 22-8774-7347.1 10 Game Mass Data Controller Storage Device 20 Bridge Network Adapter Writable Boot Removable Chip ROM Chip Embedded USB Interface FIG. 1 Controller Removable ROM Writable Boot Mass Data Storage Chip Contents 22 Chip 24 Contents Device 26 Contents First Authentication Second Authentication Game Packages Program 30 Program 32 34 First Authentication Operating System 40 Game Package Program Signature Signatures 48 36 Second Authentication Program Signature 42 First Set Public Operating System FIG. 20 Encryption Keys 38 Signature 44 Second SET Public FIG. 2A Encryption Keys 46
