Chaotic Map based Privacy Preservation User Authentication Scheme for WBANs
Shreeya Swagatika Sahoo, Sujata Mohanty · 2019
The rapid development of wireless communication technologies provides convenient and efficient online services to make life easier. Wireless body area network (WBAN) such type of service which provides a simple and low-cost strategy for health monitoring without going to the hospital. WBAN consists of a number of sensors, which embedded into the patient's body and send the collected information to the server. However, the privacy of the patient is an essential feature as the leakage of patient's sensitive data cause threats to tampering of health. This study proposes a privacy preservation user authentication scheme (PUASW) for WBAN based on the chaotic map. The formal security analysis of the scheme has been done using ROR model. In addition, PUASW can achieve several security features and can withstand several well-known attacks. AVISPA tool is used for the formal verification of our scheme. The communicational and computational cost of the proposed scheme is less compared to other related schemes.
