Problems solved by technology

However, today's wearable devices lack conventional input interfaces and special sensors to support secure pairing technology
For example, many wrist-worn fitness trackers are only equipped with vibration motors and accelerometers, and do not have touch screens to enter PIN codes, do not have light sensors to capture laser signals, and do not have microphones to record ambient sounds
Furthermore, ambient signal-based methods rely heavily on continuous ambient signals, making them vulnerable to eavesdroppers

Abstract

The invention discloses a device pairing method, which includes: acquiring vibration information of a touch device vibration, and obtaining vibration information of a wearable device measuring the vibration of a user's wearing part; wherein, the touch device is touched by the user's wearing part The vibration is triggered by scanning the vibration frequency within the preset frequency range, and the user’s touch part is triggered by touching the vibrating touch device; each vibration information is encoded separately, and the information of each vibration information is obtained. Coding sequence: when it is detected that the coding sequences of the two vibration information are identical, using the coding sequence as a shared key to establish a communication connection between the touch device and the wearable device. Correspondingly, the invention also discloses a device pairing device. By adopting the embodiment of the present invention, the security of device pairing can be improved, and the application range is wide.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a device pairing method and device. Background technique [0002] Interacting with nearby devices is an inherent feature of today's wearables due to the unobtrusive experience provided to users by many innovative applications, such as mobile payments, wireless data transfer and smart door locks. Among them, mobile payment means that the user can pay by placing the mobile phone or wearable device near the non-contact sensor; wireless data transmission refers to uploading the health and fitness data collected by the wearable device to the nearby smart phone. Mobile phone or data center; smart door lock refers to sending instructions to the door with wireless chip through the nearby smart phone or wearable device to realize the opening and closing of the door. However, the interactions between these devices contain sensitive information, making wearable devices requi...
