A security framework for e-Health service authentication and e-Health data transmission

e-Health services are gaining popularity due to largely reduced cost and wider range of advanced services. Securing e-health data transmission is challenging due to both (a) the criticality of personal medical information on effective medical treatment and privacy protection and (b) the significant computational needs of encryption algorithms. In this paper, a cost-effective security framework that suits for e-health authentication and data transmission is presented. The framework consists of efficient protocol architecture for e-health service; two risk adaptive authentication techniques and different encryption algorithms to handle data with different levels of importance, thus achieving required security requirements of e-health applications and reduction in the computational complexity and delay in e-health communication.
