摘要： Technologies for establishing and managing a connection with a power line communication network include establishing a communication connection between an electronic device and a security server. A default device encryption key associated with the electronic device is changed to correspond with a new device encryption key of the security server. Thereafter, the electronic device may only join a power line communication network of a particular security server using a network membership key, which is encrypted with the device encryption key that the particular security server associates to the electronic device. The electronic device contains a circuit interrupt to interrupt a circuit of the electronic device if the electronic device is not able to successfully decrypt the network membership key.

摘要： Embodiments of the present disclosure provide methods, apparatuses, articles, and removable storage devices for pre-boot recovery of a locked computer system. In one instance, the method includes determining on pre-boot whether a removable storage device is attached to a computer system, determining whether the computer system is in a locked state and, if the removable storage device is detected, transferring control to a pre-boot authentication module (PBA) stored on the removable storage device to interact with a manageability engine to restore the computer system from the locked state to an unlocked state. If the removable storage device is not detected, the computer system shuts down if the system is determined to be in the locked state and no other PBA is detected. The computer system comprises a host operating environment and a manageability engine that operates independent of the host operating environment. Other embodiments may also be described and claimed.

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.
