Key generation, certification and data transmission method based on physiological features

Abstract

The invention relates to a key generation, certification and data transmission method based on physiological features. The method comprises the following steps that a, physiological sensors which collect the physiological features synchronously are arranged on a human body, and one of the physiological sensors is set to be a coordinator; b, the physiological sensors extract the physiological features to obtain a first key; c, the coordinator extracts the physiological features to obtain a second key; d, the sensors carry out logical operation on the physiological feature data to be transmitted and personal codes to be transmitted and the first key and then carry out encoding, and encoded and enciphered data are obtained; e, the encoded and enciphered data are obtained and the first key are forwarded to the coordinator through relay nodes in a certain frequency or are directly transmitted to the coordinator; f, the coordinator obtains a third key according to the matched relation between the second key and the first key; g, the coordinator decodes the encoded and enciphered data through the third key and the personal codes, and finally physiological data collected by the physiological sensors are obtained. The method is easy and effective to implement, and can improve the safety of transmission of the human body physiological feature data.

Description

technical field [0001] The invention relates to a key generation, authentication and data transmission method, in particular to a key generation, authentication and data transmission method based on physiological characteristics, and belongs to the technical field of wireless communication. Background technique [0002] With the development of wireless communication technology and the maturity of sensor technology, people's attention is more focused on small human-centered networks, and some new network terms such as personal area network, home area network, vehicle networking, and wireless body area network also follow. of appearing. Wireless Body Area Network (WBAN) is a portable, mobile small network that has a significant impact on human health and lifestyle. Protecting the safe transmission of human physiological feature data collected by sensors in an environment that is not monitored, tampered and destroyed, effectively ensuring the security of personal privacy data ...
