How to process the firmware based on the firmware transmission techniques in wireless systems and devices

摘要

Embodiments of the present invention provide a method for processing firmware based on a firmware over the air technology, an apparatus, and a system. The method includes: performing check processing on at least one firmware upgrade file to fo first check data; performing encryption processing on the first check data to fo first encryption data; and combining the first encryption data, the first check data, and the firmware upgrade file to a firmware upgrade package, and sending the firmware upgrade package through an air interface to a mobile terminal. The apparatus includes: a checking module, an encrypting module, and a processing module. The system includes: a server and a mobile terminal. The embodiments of the present invention, by performing check, encryption, and combination processing on the firmware upgrade file, solves a defect in the prior art that the mobile terminal is vulnerable to intrusion of illegal codes, quickly implements upgrade of multiple pieces of firmware, and improves security of the mobile terminal.
