英文摘要： Body area network (BAN) is a key technology of solving remote medical diagnosis,mobile clinic,health evaluation and consultation, and communicity health care, which can greatly ease the outstanding contradiction of current shortage of medical resources and low utilization rate.Protecting security of vital signs information is an very important technique reqiurement in the BAN implementation process.This project aims to the characteristics of the BAN system achitecture and presents a data security scheme based on electrocardio characteristics and ultra-short channel parameters.The main research contents include designing the filter of electrocardio signal and recognizing QRS waves,exploring the retrieval theory of the channel characteristics and proposing the calculation method of the channel amplitude and phase responses,and investigating methods of the circult-level data encryption and dynamic key refreshment due to obtained electrocardio signal characteristic value and channel quantization parameters.The proposed scheme is constructed from the inherent features of the BAN system,adopts both vital information and wireless channel characteristcs to form security protection, balance the calculation complexity of the sensor nodes and smart terminal,which has advantages of high strenth,low cost and easy implementation,and is very useful to design low-power sensor nodes and provide theoretical support and enginnering implementation for forming the BAN standard system with independent intellectual property rights.
