Device data remote encryption upgrading method, storage medium and electronic device

Abstract

The invention provides a device data remote encryption upgrading method. The method comprises the steps of initializing a chip rewriting device; obtaining an encrypted upgrading file; analyzing data; checking the data; and upgrading the data. The invention furthermore relates to an electronic device and a readable storage medium, which are used for executing the device data remote encryption upgrading method. The data security of the chip rewriting device is protected in a remote upgrading encryption mode, so that the situation that a program and an authorization file in the chip rewriting device are tampered is effectively avoided; and the upgrading method is flexible, reduces the upgrading cost, ensures the upgrading correctness, is convenient in operation and ensures the upgrading data security of the chip rewriting device.

Description

technical field [0001] The invention relates to the field of chip equipment for printing consumables, in particular to a method for remotely encrypting and upgrading chip rewriting equipment data, a storage medium, and electronic equipment. Background technique [0002] As a common imaging device, a printer has played an increasingly important role in people's work and life. It uses imaging consumables (including ink cartridges, toner cartridges, etc.) to form patterns on paper. The consumables are usually equipped with a printing consumable chip for storing information about imaging materials (such as ink, toner, etc.). The printer manufacturer will set a threshold for the capacity information of the imaging material inside the chip. During the printing process, the printer records the current usage of the consumables. In some cases, when the set threshold is reached, the printer will prompt to replace new consumables. The consumable is a one-time use product, and the imag...

Problems solved by technology

For most of the original chips that are not damaged but just run out of data, they will be regarded as waste products, which is a secondary waste of resources

[0003] At present, for device data upgrades, the programs and data in the consumable chip rewriting device are generally burned into the memory of the device using a dedicated programmer; when the chip rewriting device leaves the factory, the programs and data stored in it are fixed. ; But in the remote upgrade of chip rewriting equipment, the program and data that need to be upgraded, because the data in the process of remote transmission is generally plain text, illegal traders can achieve the purpose of arbitrary tampering through the analysis of the data, and there is an urgent need for an upgrade program and data encryption methods
