IBE-Lite: A Lightweight Identity-Based Cryptography for Body Sensor Networks

Free registration required

Executive Summary

A Body Sensor Network (BSN) is a network of sensors deployed on a person's body for health care monitoring. Since the sensors collect personal medical data, security and privacy are important components in a BSN. In this paper, the authors developed IBELite, a lightweight identity-based encryption suitable for sensors in a BSN. The authors present protocols based on IBE-Lite that balance security and privacy with accessibility and perform evaluation using experiments conducted on commercially available sensors. The use of wireless sensors for health care monitoring creates new ways of providing quality health care. A diverse array of specialized sensors can be deployed to monitor for instance an at-risk patient with a history of heart attacks.
