Abstract
Implementations described herein relate to an immutable certificate for a device identifier composition engine (DICE). In some implementations, a device may include a secure computing environment. The secure component environment may include a hardware root of trust (HRoT) DICE component, a DICE layer 0 (L0) component configured to derive a DICE identity key, wherein the DICE L0 component is above the HRoT DICE component in a layer stack, a DICE layer 1 (L1) component configured to derive a DICE alias key based on the DICE identity key, wherein the DICE L1 component is above the DICE L0 component in the layer stack, wherein the DICE L1 component and the DICE L0 component are implemented as mutable code, and a controller. The controller may be configured to generate a set of certificates based on a compound device identifier (CDI).
