Abstract

The invention provides a pairing method and system and a data interaction method and system for Bluetooth equipment. The pairing method comprises the following steps: first Bluetooth equipment and second Bluetooth equipment are in wired connection through a wired interface; the first Bluetooth equipment utilizes a first random decryption factor and a second random decryption factor to generate a first Bluetooth equipment terminal link negotiation secret key, and the second Bluetooth equipment utilizes a first random factor and a second random factor to generate a second Bluetooth equipment terminal link negotiation secret key; the first Bluetooth equipment stores second Bluetooth equipment pairing information and the first Bluetooth equipment terminal link negotiation secret key to a first Bluetooth equipment pairing list, and the second Bluetooth equipment stores first Bluetooth equipment pairing information and the second Bluetooth equipment terminal link negotiation secret key to a second Bluetooth equipment pairing list; the first Bluetooth equipment and the second Bluetooth equipment are paired. Therefore, the problems caused by the Bluetooth connection mode adopted for pairing of the Bluetooth equipment are solved, and the security of data interaction between the Bluetooth equipment is further improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a pairing method and system between Bluetooth devices, and a data interaction method and system. Background technique [0002] To perform data exchange between two Bluetooth devices, it is necessary to establish a connection with each other first, and pairing is required to establish a trust relationship when the connection is established for the first time. During the pairing process, both parties need to perform multiple data exchanges. [0003] In the prior art, the data interaction in the pairing process between two Bluetooth devices is realized through the Bluetooth link. However, due to the limited transmission rate of the Bluetooth link, multiple data exchanges will take a long time, and the way of Bluetooth connection There is a risk of being attacked by a man-in-the-middle, and the wireless method is not stable enough. When the Bluetooth version is not compatible,...
