Firmware updating method and firmware updating system

Abstract

A firmware updating method is proposed. The firmware updating method includes driving a server to generate an updated firmware package, driving the server to digitally sign the updated firmware package according to a first verifying private key, driving a domain controller to encrypt the updated firmware package according to a second verifying private key, driving the domain controller to attach a patching executable profile and a limited time access token in the updated firmware package, driving the domain controller to establish a firmware birthmark identifying model, driving a computing device to confirm the effectiveness of the updated firmware package according to a first verifying public key, driving the computing device to decrypt the updated firmware package according to a second verifying public key, driving the computing device to sketch a firmware birthmark feature of the updated firmware package, driving the domain controller to identify whether the firmware birthmark feature is effective via the firmware birthmark identifying model, and driving the computing device to execute the updated firmware package when the firmware birthmark feature is effective. Thus, the firmware updating method of the present disclosure can verify whether the updated firmware package received by the computing device is safe.
