Method and system for uniformly signing product firmware

The invention provides a method and system for uniformly signing product firmware, and the method comprises the steps: receiving a signature request sent by a client through a server, carrying out the automatic uniform signature processing of all to-be-signed firmware contained in a product according to the model version of the product and the firmware type, and returning a signature result to the client. According to the automatic signature processing, signature processing can be efficiently and safely carried out on all the to-be-signed firmware, the problems that manual signature is low in efficiency and tedious in process are solved, protection of a secret key and a signature tool is achieved, the risk of leakage can be avoided, and the signature efficiency is improved. And the signature operation of all firmware is executed according to the model version and the firmware type of the product, so that the firmware can be prevented from being mistakenly swiped, and the suitability and the correctness of the
