Inventor includes Krahn, Darren, David.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: A computer-implemented method, comprising: initializing a secure component during execution of a device identifier composition engine (DICE) protocol for booting an operating system of a client computing device; determining, by a secure component, context data for a cryptographic subtask of a task associated with the DICE protocol, wherein the context data comprises a handle identifying actual data stored in a memory of the secure component, or actual data encrypted such that decryption is restricted to the secure component, wherein the determining comprises identifying the context data by the handle received from the client computing device, or retrieving the context data from an internal memory of the secure component when the handle is omitted as an optional field, and wherein the secure component is to perform the cryptographic subtask; determining, by the secure component and based on a decrypted version of the context data, a compound device identifier (CDI) value associated with the cryptographic subtask; generating, by the secure component and based on the CDI value, a CDI certificate for the cryptographic subtask; restricting access to the decrypted version of the context data to the secure component; and transferring control of the DICE protocol to a target component in the booting of the operating system by providing the CDI certificate.
