BARI+: A Biometric Based Distributed Key Management Approach for Wireless Body Area Networks

Free registration required

Executive Summary

Wireless Body Area Networks (WBAN) consists of resource constrained sensing devices just like other Wireless Sensor Networks (WSN). However, they differ from WSN in topology, scale and security requirements. Due to these differences, key management schemes designed for WSN are inefficient and unnecessarily complex when applied to WBAN. Considering the key management issue, WBAN are also different from WPAN because WBAN can use random biometric measurements as keys. The authors highlight the differences between WSN and WBAN and propose an efficient key management scheme, which makes use of biometrics and is specifically designed for WBAN domain.
