A Molecular-Based Authentication and Authorization for Internet of Things Systems

Integrating environmental and health information in the authentication and authorization processes is challenging in the Internet of things (IoT) systems using only wireless radio communications. Recent research plans for IoT future networks shed light on the need for developing new authentication techniques suitable for health care and environmental use cases. To this end, we propose a novel molecular keys (MKs)-based authentication system that uses molecules as data carriers while considering the receiver's types, concentration, and arrival time. To facilitate our proposal, we built a MK generator and detector. The system achieved a decoding accuracy of 86% for sending bit sequences within a distance of 1m. The proposed method can also accommodate dynamic authentication and authorization changes across time and places, emerging marketing applications, and evolving human activities.
