US Patent 10924277 Certifying authenticity of stored code and code updates

The authenticity and/or integrity of data is determined based on cryptographic measurements. In some cases, the data is executable code of a computer program stored in system memory. In other cases, the data is firmware stored in a storage device or a boot device. In yet other cases, the data is executable code that is part of an update being received by an application controller. For example, the update may be a secure over-the-air (SOTA) update of software stored in firmware (e.g., on a storage device or a boot device).
