Comparative Survey of Key Management Schemes for Body Area Networks

J. Mohana, V. Thulasibai


A number of tiny sensors are placed or implanted on the human body to form a network called as Wireless Body Area Networks (WBANs). The function of the network includes the monitoring of the vital physionlogical values and communicating it to the physician for early diagnosis. The transmitted parameters are the personal record of a patient which demands security and privacy. It is an open issue to provide security to these kinds of networks since they are limited in together energy and power resources. Key establishment is an essential service for protected communication between a central device and each biosensor implanted in the human body. Though there are number of schemes, key generation using physiological values is considered to be efficient. The paper provides a biometric system to simulate ECG signals and also gives a comparative survey of various key establishment schemes using physiological values. The False Acceptance Rate (FAR) and False Rejection Rate FRR) are the performance metrics taken for the comparison.
