Problems solved by technology

The prior art bluetooth interaction relies on the security mechanism of the bluetooth protocol itself, and the obvious disadvantage is that there is a case of loss of bluetooth data, especially when communicating between mobile smart devices and smart password devices, there is a risk of data being intercepted and cracked

Embodiment Construction

[0010] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended...

Abstract

This application discloses a control method for Bluetooth communication interaction, which includes: a smart mobile device sends a data packet to a smart cryptographic device through Bluetooth, and the data packet is composed of a command header and a data field; after the smart cryptographic device receives the data packet, it first verifies Command header, and then verify the data field, if the verification of the command header is successful, the smart password device executes the business instruction, returns the result of the business instruction, and returns a status packet, the status packet includes the status header, if the verification command header is wrong, the smart password The device does not execute the business instruction, but returns the status packet header; the smart password device sends the status packet to the smart mobile device through Bluetooth communication; the smart mobile device verifies the status packet, and judges whether the first byte of the status packet header is the first byte number or the second The number of bytes, the smart cryptographic device executes business instructions. The invention has the advantages of adopting encrypted communication of command data, improving the confidentiality of data communication, and effectively resisting the theft and tampering of sensitive information during transmission.

Description

technical field [0001] The invention relates to a control method for bluetooth communication interaction. Background technique [0002] Bluetooth communication was originally designed to facilitate low-cost, low-power wireless communication connections between mobile devices and accessories, and has now become the IEEE802.15 standard. The general bluetooth system structure consists of three parts: the bottom hardware module, the intermediate protocol layer and the application layer. The bottom hardware module includes the baseband layer, the link management layer and the radio frequency layer. The interpretation of the control interface (HCI) is transmitted. The intermediate protocol layer usually includes logical link control and adaptation protocol, service discovery protocol, serial port emulation protocol, etc., and the application layer generally corresponds to various application models and applications. The existing technology relies on the security mechanism of the ...
