What is User Impersonation Attack

Cloud technology and internet of things (IoT) is a quickly developing computing technology through which resources are shared via internet. IoT facilitates seamless interactions between humans and heterogeneous devices including personalized healthcare systems. It has the potential to provide ensure supervision of the elderly, telemonitoring, teleconsultations, and computer-assisted rehabilitation. These healthcare services allow easy access of patient data in real time. However, IoT-based remote patient monitoring and other healthcare applications are growing fast; the hurdle to its growth is security. This chapter proposes a novel remote user authentication scheme for IoT-enabled healthcare applications. The scheme is lightweight and robust to attacks and also has low computational overhead. The proposed scheme satisfies the desired essential attributes of security. A formal verification performed using ProVerif proves the security of the scheme.
