    Abstract: A data processing system supporting a secure domain and a non-secure domain comprises a hardware component, and a processor device having operating modes in the secure domain and non-secure domain, the processor device to execute a secure application in the secure domain. The hardware component has a property having a secure state. The property of the hardware component in the secure state may only be reconfigured responsive to instructions received from the secure domain. The secure application is operative to implement a configuration service to configure the property of the hardware component in the secure state, responsive to a request received from the non-secure domain according to an application programming interface associated with the secure application.

    Abstract: An electronic device for management of cryptographic keys, and a corresponding method implemented in a computing device comprising a physical processor, transmit feature data of the device to a key generation module, wherein the feature data comprises information corresponding to an identifier or an attribute of the device, and receive, by the device from the key generation module, a digital signature of the transmitted feature data. The device installs the received digital signature as a cryptographic private key for communication, and performs a cryptographic operation using the installed digital signature as the cryptographic private key.
