Method and device for realizing safe interaction and pairing authentication between Bluetooth devices

Abstract

The invention discloses a method and device for realizing safe interaction and pairing authentication between Bluetooth devices, and belongs to the field of information safety. The method comprises the following steps: when a client searches a Bluetooth broadcast packet, establishing a connection between a Bluetooth device, and generating a random number and transmitting the random number to the Bluetooth device; generating a Hash value by the Bluetooth device according to the random number and transmitting the Hash value to the client; when the client judges that the received Hash value is right, then generating a pairing code and displaying the pairing code according to the Hash value, and transmitting a pairing request to the Bluetooth device; generating a pairing code by the Bluetooth device according to the conserved Hash value and prompting a user to perform a pairing code comparison; and when the Bluetooth device detects that a confirm key is pressed down, then the paring is successful. By adopting the technical method of the invention, in the pairing process, the user does not need to select the Bluetooth device manually, thus the operation is simple and a misoperation can be prevented, the accuracy is high, and a hardware operation and a human-computer interaction are added in the pairing authentication process, therefore, the interaction and pairing authentication between the Bluetooth devices can be realized and the safety of pairing can be improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for realizing secure interactive pairing authentication between Bluetooth devices. Background technique [0002] The pairing process between existing Bluetooth devices is relatively complicated. When establishing a connection between Bluetooth devices, you must first scan the Bluetooth information of both parties, select the Bluetooth device to be matched, and then enter the pairing code recognized by both parties and pass the verification. establish connection. [0003] When there are multiple pairable devices in the use environment, the user must know the name of the terminal device to be paired, and it is easy for the user to make a wrong operation when manually selecting, or even connect the wrong device. The hardware function is used, the security is low, and since the pairing code needs to be entered for verification every time the connection is made...

[0003] When there are multiple pairable devices in the use environment, the user must know the name of the terminal device to be paired, and it is easy for the user to make a wrong operation when manually selecting, or even connect the wrong device. The hardware function is used, the security is low, and because the pairing code needs to be entered for verification every time the connection is made, the pairing operation process is cumbersome, the accuracy is poor, and the usability is poor
