    Abstract: 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

    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
