Abstract

The embodiment of the invention provides a chip authentication method, a system, a printer, a consumable chip and consumable box. On one hand, according to the embodiment of the invention, the printer sends an authentication instruction to the consumable chip; the authentication instruction includes a designation code which is compiled in accordance with a program compilation format of the authentication consumable chip; the consumable chip receives the instruction sent by the printer, and identifies whether the received instruction is an authentication instruction; if the received instruction is identified as the authentication instruction, the consumable chip runs a designation code and obtains the running results; and the consumable chip returns the running result to the printer, and the printer receives the running result and judges whether the consumable chip is an authentication consumable chip. Therefore, the technical scheme provided by the embodiment of the invention can solve the problem of security vulnerability of an authentication method for the consumable chip by the printer in the prior art.

Description

【Technical field】 [0001] The invention relates to the technical field of printing and imaging, in particular to a chip authentication method, system, printer, consumable chip and consumable box. 【Background technique】 [0002] At present, when the printer authenticates the consumable chip in the consumable box, the consumable chip is generally in slave mode. Specifically, the consumable chip only needs to receive the authentication instruction sent by the printer. This authentication instruction is generally used to indicate some specific algorithms and specific data. Then, the consumable chip processes these specific data according to these specific algorithms to obtain processing results. The processing result is fed back to the printer, and the printer determines whether the authentication of the consumable chip is successful according to the processing result. [0003] In the course of realizing the present invention, the inventor finds that there are at least the follo...
