Abstract

The invention discloses a lightweight real-time key generation method based on behavior motion perception in an internet of things wearable equipment. The method comprises the following steps that sensing data of acceleration sensors embedded in different wearable equipment of the user are acquired, wherein the sensing data are the acceleration data which are generated by different wearable equipment through random shaking together and have similar trajectories; high-pass filtering is performed on the acquired sensing data and mobile smooth filtering processing is performed; error correction filtering is performed on the sensing data of different wearable equipment, and the concrete process is that the bit sample points of which the adjacent difference value is less than the threshold are discarded; bit quantification is performed on the sensing data after error correction filtering by a data bit quantification algorithm based on the numerical relationship of adjacent data points; and two sets of wearable equipment performs negotiation so as to co-own the same security key.

Description

technical field [0001] The invention relates to the field of Body Sensor Network in the Internet of Things, in particular to a lightweight dynamic key generation method for a wearable computing embedded device in a Body Sensor Network. This includes initial key generation between wearable devices, sensor data processing, and real-time session key generation. Background technique [0002] With the current development of wireless sensor networks and wearable computing technology, wearable and embedded devices are widely used in different fields (including telemedicine). The security issue of wearable devices has received more and more attention. Since the data involved in these devices worn on the human body involves the user's personal privacy, it is very important to ensure the communication security between devices in the body domain sensor network. On the other hand, due to the limited application characteristics of wearable devices, their hardware capabilities such as o...
