Group key management for secure multicasting in internet of things (IOT) by using secret sharing techniques

Internet of Things (IoT) is tied in with connecting actual items to the worldwide network (internet) in which information detected by these articles become accessible and distantly open. Group communication discovered to be more productive in utilizing assets than pairwise communication. Group key establishment is vital for secure the communication of the multicast group and give message secrecy, credibility, and integrity. Traditional Secret Sharing schemes use polynomials for generating/reconstructing the shares of the secret S which is considered computationally substantial. AVISPA is a software tool that is generally used to naturally approve the security of internet protocols and applications. We can conclude that the security analysis and the performance evaluation comparison between the proposed scheme and other IoT group key establishment schemes showed that our scheme accomplishes better security and use the network and gadgets assets effectively.
