摘要： PROBLEM TO BE SOLVED: To provide a mechanism for a protected operating system boot which prevents rogue components from being loaded with an operating system, and thus prevents divulgence of a system key under inappropriate circumstances. SOLUTION: After a portion of a machine startup procedure has occurred, the operating system loader is run, the loader is validated by a validator, and a correct machine state is either verified to exist and/or created. Once the loader has been verified to be a legitimate loader, and the machine state under which it is running is verified to be correct, the loader is carried out. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To prevent rogue components from being loaded together with an operating system, to prevent divulgence of a system key under inappropriate circumstances. SOLUTION: After a portion of a machine startup procedure has occurred, an operating system loader is run, and the loader is validated, and a correct machine state is either verified to exist and/or to be created. Once the loader has been verified to be a legitimate loader and the machine state under which the loader is running is verified to be correct, a loader's future behavior is known to protect against the loading of rogue components that can cause divulgence of the system key. When the loader's behavior is known to be safe for the system key, a validator unseals the system key and provides it to the loader. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：为了防止流氓组件与操作系统一起加载，以防止在不适当情况下泄露系统密钥。
解决方案：在机器启动过程的一部分发生之后，运行操作系统加载程序，验证加载程序，并验证是否存在和/或创建正确的机器状态。一旦加载程序被验证为合法的加载程序，并且加载程序正在运行的机器状态被验证为正确的，装载器的未来行为是已知的，以防止可能导致系统密钥泄露的流氓组件的加载。当装载机的行为已知对于系统密钥是安全的时，验证器将打开系统密钥并将其提供给加载程序。版权所有（C）2006，JPO＆NCIPI

摘要： Data such as a musical track is stored as a secure portable track (SPT) which can be bound to one or more players and can be bound to a particular storage medium, restricting playback of the SPT to the specific players and ensuring that playback is only from the original storage medium. The SPT is bound to a player by encrypting data of the SPT using a storage key which is unique to the player, is difficult to change, and is held in strict secrecy by the player. The SPT is bound to a particular storage medium by including data uniquely identifying the storage medium in a tamper-resistant form, e.g., cryptographically signed. The SPT can also be bound to the storage medium by embedding cryptographic logic circuitry, e.g., integrate circuitry, in the packaging of the storage medium. The SPT is bound by encrypting an encryption key using the embedded logic. By using unique cryptographic logic, only that particular storage medium can decrypt the encryption key and, therefore, the data of the SPT encrypted with the encryption key. To allow a user to playback the SPT on a number of players, players can share storage keys with one another. Such key sharing is done in a cryptographically secure manner. Before downloading an SPT to a particular external player, the ability of the external player to enforce restrictions placed upon the SPT is verified.
