Abstract
Systems, devices, and methods are provided for cryptographic co-dependent across multiple roots of trust. A device may comprise two or more co-dependent roots of trust, such as a trusted execution environment (TEE) of a main application processor and a cryptographic subsystem comprising a cryptographic processor. A server may validate digital signatures generated by each co-dependent root of trust that is known for the device and then provide the device with cryptographic material that can be used to establish a shared secret. The shared secret may be used by the device to request the performance of a sensitive operation.
