    摘要： A method, apparatus, system, and computer program product for a secure subscriber identity module service. Communication via a mobile network is activated in response to receiving a request to activate communication service for the system by a secure partition of the system. In response to receiving the request, a key is retrieved for a permit service from storage accessible only by the secure partition. The key is included in a permit requesting to activate the communication service, and the permit is sent to a service provider for the communication service. The service provider communicates with the permit service to obtain a digital signature for the permit. The secure partition receives a signed permit from the service provider, confirms that the signed permit contains the digital signature by the permit service, and activates the communication service for the system in response to confirming that the signed permit contains the digital signature.

    摘要： A method, system, and computer program product for a host software tamper detection and protection service. A secure partition that is isolated from a host operating system of the host system, which may be implemented by firmware of a chipset of the host system, obtains file metadata from the host system and uses the file metadata to identify a first file for examination for tampering. The secure partition obtains data blocks for the first file, communicates with a service via an out-of-band communication channel, and uses information obtained from the service and the data blocks to determine whether the first file has been corrupted. The secure partition obtains the file metadata and the data blocks for the first file without invoking an operating system or file system of the host system.
