Secure and efficient e-health scheme based on the Internet of Things

Internet of Things is a new generation of network service platform that allows everyday objects including small devices in sensor networks to be capable of connecting to the internet. Such an innovative technology can lead to positive changes in human life. An e-health service based on the Internet of Things has great potential. The popularity of intelligent mobile medical devices, wearable bio-medical sensor devices, cloud computing, and big data analysis have dramatically changed the usage pattern and business rule of e-health services based on the Internet of Things. The rapid development of e-health services based on the Internet of Things poses risks in security and privacy. In this study, we propose a new security scheme for an e-health service. This scheme allows both the local base station and hospital cloud server to authenticate each other, to secure the collection of health data. Our scheme uses the crypto hash function to check the integrity of authentication exchanges. In addition, it provides mutual authentication with anonymity and terminates with a session key agreement between each local base station and the hospital cloud server. To assess our scheme, we conduct performance and security analysis. Results show that our scheme is secure, lightweight, and resistant to different types of attacks.
