Abstract
A root of trust is established between a cloud and an edge device that communicates with the cloud. The root of trust may be embodied as a secret device key securely stored by the edge device and the cloud. The edge device receives arbitrary cloud modules (workloads) that include guest/tenant code that may communicate with the cloud and possibly local/leaf devices connected to or included with the edge device. The edge device extends or diversifies the root of trust to the cloud modules based on the device key. New keys are derived from the device key. The new keys are used to sign credentials (e.g. tokens or certificates) for the respective cloud modules. This provides each cloud module with its own trusted unique cloud identity that can be verified by the cloud using the cloud's copy of the device key.
