Abstract

The invention discloses a terminal firmware update method and device. The method includes: when receiving a firmware update instruction, the terminal performs a two-way identity verification with a source host providing firmware update data; when the two-way identity verification between the terminal and the source host When the verification is successful, the terminal receives the encrypted update data sent by the source host, where the encrypted update data is generated by the source host based on the authentication key encryption firmware update data generated during the two-way identity verification process; the terminal verifies whether the received encrypted update data is the source The legal update data sent by the host; when the encrypted update data received by the terminal is the legal update data sent by the source host, the terminal performs firmware update based on the received encrypted update data. The present invention improves the terminal firmware update mode in terms of the identity of the sender of the firmware update data, transmission security and data legality, greatly improves the data and process security of the firmware update, and avoids the leakage of sensitive information inside the terminal product.

Description

technical field [0001] The present invention relates to the technical field of firmware update, in particular to a terminal firmware update method and device. Background technique [0002] Firmware update refers to upgrading the embedded firmware of portable terminal products such as touch screens, communication devices, and players. Firmware update can improve the functions of terminal products, enhance the stability of terminal products, and repair technical vulnerabilities of terminal products. [0003] The firmware program update of traditional terminal products only realizes the firmware program update. In most application fields, this firmware program is completely open, and the firmware is not kept secret. When the firmware is updated, the firmware program is updated from the source host (or server) to the user terminal in plain text. [0004] However, in terminal products in special fields such as military, aviation, finance, etc., the firmware program of the termin...
