Internet of Things (IoTs) devices face power constraints, manufacturers increasingly focus on group communication for their applications.Such communication heavily relies on a dependable, efficient, and verifiable group secret key.Blockchain technology has the power to solve the problems because it is decentralized, secure, and private.The Internet of Things poses unique challenges for authentication and key management methods due to resource constraints and placement of constituent devices in places where physical access to the devices is possible.This paper introduces an innovative authenticated key management system for Cloud-Assisted Industrial Internet of Things.The protocol addresses the issue of a single point of failure while preserving the security attributes of the existing system.We propose ways for implementing lightweight authenticated key management schemes that are specifically designed for various design processes.Atechnique that requires authentication is implemented using elliptic curve and hash algorithms.This scheme also offers the functionality of adding and removing clients, as well as ensuring the freshness of keys.We conducted an empirical investigation using a proposed method and evaluated its performance using the Scyther verification tool.The topics of security analysis and computational complexity have also been addressed.We conclude by outlining potential future research directions.
