Abstract

The embodiment of the invention discloses an OTA (over-the-air) firmware upgrading method, device and equipment. The method comprises the steps of: splitting a to-be-upgraded firmware into N data packages, carrying out hash operation on the N data packages respectively to obtain N server hash values; sequentially sending the N data packets and the N server hash values to an Internet of Things device; and if an interrupt message sent by the Internet of Things device is received, stopping sending the data packets and the server hash value to the Internet of Things device. By adoption of a technical scheme provided by the embodiment of the invention, a network transport protocol data package field is redefined, the single-package continuous verification function is realized, when the data package is attacked or tampered, data transmission is interrupted in time, and the resource overhead is saved in comparison with a mode of performing overall verification after the data is completely transmitted. Besides, a multi-encryption mode is adopted, data encryption and Internet of Things device identity verification are carried out respectively, and the security of the firmware transmission process can be further ensured.

Description

Technical field [0001] This application relates to the field of Internet of Things technology, and in particular to an OTA firmware upgrade method, device and equipment for an over-the-air download technology. Background technique [0002] With the development and large-scale deployment of 5G networks, the number of IoT devices is increasing exponentially. However, many Internet of Things devices are installed in places that are difficult for operators to access, and are widely dispersed and difficult to manage. This brings a lot of trouble to equipment upgrades. Over-the-Air Technology (OTA) downloads through the wireless network, which can quickly realize the remote update of the firmware of the Internet of Things device, and is an important part of the design of the Internet of Things. [0003] The OTA firmware upgrade technology for IoT devices has been developed for many years, but with the enhancement of device firmware attacks, the firmware security during the OTA upgrade p...
