Geometric Authentication Mechanism for Enhancing Security in IoT Environment

In the Internet of things (IoT) environment, many applications access services through remote methods. In this paper, we designed a new geometric authentication mechanism to enhance security. The solution is based on geometric characteristics to achieve rapid authentication at low computational cost. In addition, we use the user’s biometrics to improve the security level of the system. Our solution meets the following security features: anonymity, resistance to forgery attacks and replay attacks, fast error detection, resistance to offline password guessing attacks, resistance to server overload attacks, mutual authentication, session key agreement, and flexibility in users choosing and changing their passwords easily.
