The recent surge in the number of machines, appliances, and services connected to the Internet demands secure processing and transmission of sensory data. Authentication plays a crucial role in a typical security model used in the Internet of Things (IoT), and it protects data communications from various attacks, such as impersonation and denial of service, by verifying and allowing legitimate users to access the IoT resources. However, recent authentication literature has not addressed the need for developing a scalable and efficient authentication method in this field. This paper proposes a secure and anonymous ticket-based authentication method for the IoT. The proposed method protects the network from various security and privacy threats such as data alternation and denial of service while also offering mutual authentication and sensor anonymity. Our security and performance evaluations confirm the improvement.
