Polynomial based light weight security in wireless body area network

Wireless body area networks have grown more attention in healthcare applications. The development of WBAN is essential for tele medicine and Mobile healthcare. It enable remote patient monitoring of users during their day to day activities without affecting their freedom. In WBAN, the body sensors in and around the patient body that collect all patient information and transferred to remote server through wireless medium. The wearable sensors are able to monitor vital signs such as temperature, pulse, glucose information and ECG. However there are lots of research challenges in WBAN when deployed in the network. The sensors have limited resources in terms of memory, size, memory and computational capacity. The WBAN operation is closely related to patient´s sensitive medical information. Because, the unsecured information will lead to wrong diagnosis and treatment. The security is important thing in wireless medium. In WBAN, the unauthorized people can easily access the patient´s data and data can be modified by the attackers. The creation, deletion, modification of medical information needs a strict security mechanism.
