More Information
Summary:Aspects of the present disclosure relate to an apparatus comprising TEE circuitry configured to maintain a list of trusted devices, and interface circuitry to provide communication between the TEE of the apparatus and TEE circuitry of a device communicatively coupled to the apparatus. The TEE circuitry of the apparatus is configured to perform, with the TEE circuitry of the device, a remote attestation in respect of the TEE circuitry of the device. Responsive to a positive outcome of the remote attestation, the device is added to the list of trusted devices. The TEE of the apparatus receives, from the TEE circuitry of the device, an indication of one or more further devices which are trusted by the device, and adds said one or more further devices to the list of trusted devices.
