Abstract

There is provided a method for enabling power origin labeling processing with increased security in an industrial context. The method comprises: providing, at a device configured to generate power origin labels, a hardware-protected storage for storing signing keys that are bound to the device and that are to be used by a power origin labeling algorithm for calculating the power origin labels; providing, at the device, a trusted execution environment, TEE, for the power origin labeling algorithm to be implemented and/or executed in the TEE; and providing, at the device, a remote attestation mechanism for an external party to verify the power origin labeling algorithm and/or the device.
