Query: Sensor Networks in Healthcare: Ensuring Confidentiality and User
  Anonymity in WBAN   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.
