Sensor Networks in Healthcare: Ensuring Confidentiality and User Anonymity in WBAN
This addresses privacy and security concerns for healthcare users of WBANs, but it is incremental as it modifies an existing protocol.
The paper tackles the security flaw in Bluetooth Low Energy (BLE) pairing protocols used in Wireless Body Area Networks (WBANs) by proposing a new pairing protocol based on Lightweight Anonymous Authentication Protocol (LWAA), resulting in a 3.8% power overhead.
Wireless body area network(WBAN) is becoming more popular in recent years. Security and privacy of this network is the major concern for the researchers. Most of the WBAN sensors currently available in the market uses Bluetooth Low Energy (BLE) protocol for connection. But the BLE protocol has an inherent security flaw due to its weak pairing protocol which can be easily be exploited by an attacker. In this paper, a different pairing protocol based on Lightweight Anonymous Authentication Protocol (LWAA) is proposed. Proposed protocol has a 3.8% power overhead over traditional BLE. But this is a very small price to pay if we consider all the benefits it brings to the system.
