Dual Encryption Scheme-based Secure Group Key Management for IoMT Communication Networks

Abstract

The Internet of Things (IoT) plays a vital role in modern communication, where security is a major concern. This paper proposes a group key management approach using a dual encryption scheme (AES and RSA) to ensure secure communication in an Internet of Medical Things (IoMT) environment. Doctors and patients /devices act as network members in a group, exchanging data securely by using group keys. A group key is valid for 72 hours to enhance security and prevent unauthorized access. This proposed group communication system is implemented /simulated using NS3 simulator and its performance is evaluated by using metrics such as packet delivery ratio, throughput and delay. Results show that the proposed system provides secure and efficient communication in IoMT environment.
