Chaotic Map based Privacy Preservation User Authentication Scheme for WBANs,17- 20 October 2019

Abstract

With the advancement of network and communication technologies, the Internet plays a vital role in our day to-day life. These technologies provide several online services such as online booking, gaming, online shopping, e-health care, etc. WBAN such type of e-healthcare systems which consists of several sensors implanted in patient’s body. These sensor nodes collect various health-related sensitive data such as heart rate, blood pressure, pulse rate, etc. and send them to the network server for processing However, as the information is communicated through the open channel, security and privacy of the shared information remain a paramount concern. Thus, authentication is essential to verify the legitimacy of the communicating parties. In this work, we proposed a mutual authentication system for WBANs. The formal security analysis of the proposed scheme has been done using the Real Or-Random Model (ROR). In addition, the informal security analysis of the scheme proves that it can withstand several known attacks. Moreover, the scheme is also efficient in terms of computation and communication cost compared to other existing schemes.
