摘要： A system may include a printed circuit board, a first component located on the printed circuit board, the first component having a first unique identifier and a processor located on the printed circuit board, the processor including a one time programming section. The processor may acquire the first unique identifier from the first component and store the first unique identifier in the one time programming section during the first time initialization. Upon subsequent initializations, the processor may acquire the first unique identifier from the first component and compare the first unique identifier to the stored first unique identifier. The processor may allow the subsequent initializations to proceed if the first unique identifier matches the stored first unique. The processor may disallow the subsequent initializations from proceeding if the first unique identifier does not match the stored first unique identifier.

摘要： A technique for authenticating software in a computer system is provided that can be used to prevent unauthorized users from accessing or using certain features or resources of the computer system. In accordance with the technique, a relatively small hash table is authenticated at system boot up and then used during run-time to authenticate selected portions of a software image. The technique advantageously permits software to be authenticated in a manner that does not impose significant delays upon the boot-up time associated with the computer system. The technique is applicable to both general-purpose and special-purpose computer systems, including embedded systems.
