A Study of Hierarchical Group Key Management: Enhancing Data Security in Cloud Communication

Abstract

Data security in the cloud is where the majority of the most recent work has focused its attention.For safe data transfer in a cloud context, a new key management method that allows for multicastcommunication must be presented. The study proposes a novel hierarchical key management techniquesuitable for multicast communication in the cloud. For big, ever-changing multicast systems, the suggestedapproach is the best option due to its efficiency and scalability. Managing access control to approve andauthenticate users utilizing the data is another significant difficulty in a cloud setting. The paradigm ofaccess control used in a conventional setting is very different from that used in the cloud. Therefore,encryption methods, in addition to the access control strategy, must be implemented to safeguard data ingroup communication.
