Problems solved by technology

Since the firmware is downloaded separately, its signature will not be verified. Therefore, for the above firmware upgrade method, if the upgrade protocol of the module manufacturer is leaked, the upgrade tool can be forged, and the firmware of the module may be illegally upgraded, resulting in communication data leakage. security risk

Abstract

The present disclosure relates to the technical field of payment terminals and provides a method and a device for upgrading a module firmware of a POS machine in order to improve safety of the POS machine when upgrading the module firmware. The method comprises: downloading a module firmware upgrade package; verifying a signature of the module firmware upgrade package; and decompressing the module firmware upgrade package to perform subsequent upgrading of a module firmware if a verification of the signature of the module firmware upgrade package is successful, or otherwise, returning information that the verification fails.

Description

technical field [0001] The invention belongs to the field of payment terminals, and in particular relates to a method and a device for upgrading the firmware of a POS machine module. Background technique [0002] A payment terminal (Point Of Sale, POS) machine includes multiple modules, such as magnetic stripe card, contact IC card reader, contactless IC card reader, Wifi, Bluetooth, 2G, 3G, 4G, camera , printers and barcode scanning heads, etc. Among these modules, some modules, such as contact IC card readers and non-contact IC card readers, do not have their own firmware (Firmware), but are driven by (Operating System, OS). It is carried out by upgrading the OS, and some modules, such as 2G, 3G, and 4G modules, have their own firmware and their own Flash for storing firmware. These modules are connected to the POS machine through serial ports, USB, etc., and their firmware needs to be downloaded separately. . [0003] At present, when the POS machines on the market upg...
