Privacy Preserved Medical Service Provider Selection in Cloud-based WBAN
Abstract
\n Continuous health status monitoring of the persons equipped with Wireless Body Area Network (WBAN) is one of the key emerging technologies in the area of e-healthcare. In this technology, WBANs and Medical Service Providers (MSPs) are connected via a cloud infrastructure, where WBAN continuously uploads the present readings of physiological parameters via base station such as smart phone, smart watch, etc. Cloud analyzes the physiological parameters and whenever any medical emergency of the user is detected, it checks the infrastructural parameters including the location information of all MSPs connected to it and finds the most appropriate MSP to handle the\n\nmedical emergency. This MSP selection task has to be performed efficiently so that the medical treatment of the user can start as early as possible. In the existing works, a trusted third party, namely, trusted authority (TA) actively participates in the MSP selection process, which may take undue advantages. The aim of the work in this paper is to remove the role of TA during MSP\n\nselection process. However, TA will participate in the system setup phase such that it cannot obtain any advantage in compromising the MSP selection task. The proposed scheme has been scrutinized through an adversary model and simulated using ProVerif tool to verify the security and privacy.
