The fixed trusted module contains a digital certificate, which includes a platform key used to verify a first boot module, and a package verification key used to validate authenticity of an image update file. The dynamic trusted image module contains a platform certificate signed by the signing key. The platform certificate includes a platform verification key used to validate at least one of (i) a second boot module, (ii) an operating system loader, (iii) an operating system, or (iv) a file system. The platform certificate also includes image information associated with one or more images stored in the platform certificate, key information associated with one or more public keys, and electronic device-specific data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Trusted modular firmware update using digital certificate","description":"An electronic device includes a boot memory, a hardware memory programmed with a signing key, and a processor configured to implement a fixed trusted module and a dynamic trusted image module.
