Security awakening device and method for wireless body area network sensing node

Abstract

The invention discloses security awakening device and method for a wireless body area network sensing node, which mainly solve the problems of large energy consumption and poor security of the prior wireless body area network sensing node. The security awakening device comprises a wireless trigger circuit, an awakening authentication code comparing circuit and a main circuit, wherein the wirelesstrigger circuit obtains energy from an awakening signal transmitted by a wireless body area network controller and respectively transmits the energy to the awakening authentication code comparing circuit and the main circuit; the awakening authentication code comparing circuit compares an awakening authentication code in the awakening signal with the awakening authentication code stored in the wireless body area network sensing node and judges whether the main circuit is triggered or not; and the main circuit receives a trigger signal of the wireless trigger circuit to establish data communication with the wireless body area network controller and feeds back a new awakening authentication code to the awakening authentication code comparing circuit for use during awakening at next time. Theinvention has the advantages of less energy consumption and high security and can be used for awakening the sensing node in a wireless body area network.

Description

technical field [0001] The invention belongs to the technical field of communication, relates to a safe wake-up device and method, and is suitable for node wake-up in a wireless body area network. Background technique [0002] Wireless Body Area Network (WBAN), that is, Wireless Body Area Network, is a communication network centered on the human body and composed of network elements related to the human body. Through WBAN, people can communicate and synchronize with the electronic devices they carry. WBAN will turn the human body into a part of the communication network, so as to truly realize the ubiquity of the network. Wearable computing and ubiquitous computing will also become a basic feature of people's daily life with the popularization and application of WBAN. [0003] The wireless body area network based on low-consumption wireless sensor network technology is mainly used for remote sensing and monitoring of personal life activities, which can bring great convenie...

Problems solved by technology

However, this method does not consider the protection of the wireless wake-up circuit. If an external user, whether intentionally or unintentionally, can wake up the sensor device in the wireless body area network through a radio signal at will, resulting in information loss, leakage, power consumption, even the failure of sensor nodes

Therefore, the security problem is an important problem to be solved urgently in the wireless wake-up method
