Security Framework for Authentication and Integrity Verification in IoT-WSN Healthcare Applications

Rapid adoption of Internet of Things (IoT) has introduced critical problems, particularly related to security and privacy. The heterogeneous characteristics of IoT makes authentication difficult since ensuring both efficiency and security simultaneously remains challenging. This paper proposes a security framework for authentication and integrity for IoT-WSN Healthcare applications. The proposed framework employs a three-layer IoT architecture that includes the IoT layer, Edge layer, and Cloud layer. It consists of two phases. In phase-1, Two-factor authentication is performed in which device registration is done initially, followed by device ID based authentication. In phase-2, Hash based data integrity checking is performed using the hashing technique, Spongent. Experimental results have shown that the proposed framework attains improved throughput and reduced energy consumption, when compared to other schemes.
