    摘要： Machine instructions comprising a bootstrap code are buried within a critical component of an electronic game console where they cannot readily be accessed or modified. A preloader portion in a read only memory (ROM) is hashed by the bootstrap code and the result is compared to an expected hash value maintained in the bootstrap code. Further verification of the boot-up process is carried out by the preloader, which hashes the code in ROM to obtain a hash value for the code. The result is verified against a digital signature value that defines an expected value for this hash. Failure to obtain any expected result terminates the boot-up process. Since the bootstrap code confirms the preloader, and the preloader confirms the remainder of the code in ROM, this technique is useful for ensuring that the code used for booting up the device has not been modified or replaced.

    摘要： Software is licensed for use on a particular computing device, such as a gaming console or a multimedia console. An unlocking code is provided from a distribution service to the computing device (either directly or via a user), which in turn, unlocks the appropriate software or portion of software for use with the associated computing device. The software may reside on a computer-readable medium, such as a CD-ROM or DVD disk, that is being used in conjunction with the computing device. The unlocking code may be provided directly to the user in private (e.g., via email or a mobile phone) or in public (e.g., published on a website). Portions of the software that may be unlocked include a particular level of a game or other features (such as additional characters or weapons), or a working or more advanced version of an application that was otherwise provided as a demo or older version. The unlocking code may be based on a unique identifier of the computing device and an identifier associated with the software seeking to be accessed. Thus, the code may only be used by the computing device having that unique identifier. This prevents unauthorized or unlicensed computing devices from using the software.

    摘要： Manifest-based trusted agent management in a trusted operating system environment includes receiving a request to execute a process is received and setting up a virtual memory space for the process. Additionally, a manifest corresponding to the process is accessed, and which of a plurality of binaries can be executed in the virtual memory space is limited based on indicators, of the binaries, that are included in the manifest.

    摘要： Transferring application secrets in a trusted operating system environment involves receiving a request to transfer application data from a source computing device to a destination computing device. A check is made as to whether the application data can be transferred to the destination computing device, and if so, whether the application data can be transferred under control of the user or a third party. If these checks succeed, a check is also made as to whether the destination computing device is a trustworthy device running known trustworthy software. Input is also received from the appropriate one of the user or third party to control transferring of the application data to the destination computing device. Furthermore, application data is stored on the source computing device in a manner that facilitates determining whether the application data can be transferred, and that facilitates transferring the application data if it can be transferred.
