Problems solved by technology

[0003] The existing wireless keyboards generally do not perform security authentication when they are connected to the host, that is, the security authentication with the host cannot be realized, and there are certain hidden dangers in information security
If encryption technology is used, complex encryption technology will take up a lot of hardware resources and increase costs
[0004] In addition, in the prior art, large-capacity external memory needs to be connected to the host through data lines, resulting in many interfaces and inconvenient connection

Abstract

The invention discloses a wireless keyboard based on NFC certification and an implementation method, and aims at quickly and conveniently achieving certification between a safe keyboard and a host. According to the technical scheme, the wireless keyboard comprises a wireless keyboard body (12) which is communicated with the host in a wireless mode and an NFC module (13) which is in signal connection with a processor (121) arranged in the wireless keyboard body. According to the wireless keyboard based on NFC certification and the implementation method, the NFC module conveniently achieves the pairing and certificating process with the host with an NFC module, a success certification signal is sent to the processor arranged in the wireless keyboard body, the processor enables a wireless communication module arranged in the wireless keyboard body to conduct signal transmission with the host after receiving the success certification signal, and reliability and safety of information transmission are guaranteed.

Description

technical field [0001] The invention relates to wireless keyboard technology, in particular to a wireless keyboard based on NFC authentication. Background technique [0002] At present, the wireless keyboard is a mature technology. The wireless keyboard communicates with the host computer wirelessly. Its main body includes buttons, processors, wireless communication modules and power circuits. powered by. The processor receives information input by the user through keys, and the processor also has a signal connection with the wireless communication module. [0003] The existing wireless keyboard generally does not carry out security authentication when it is connected to the host, that is, the work such as security authentication with the host cannot be realized, and there are certain hidden dangers in information security. If encryption technology is used, complex encryption technology will occupy a large amount of hardware resources and increase costs. [0004] In addit...
