Secure and Efficient Anonymous Group Data Sharing by SBIBD Technique in Cloud Environment

Abstract

In recent decades, group data sharing in cloud systems has been a prominent issue. With the rise in popularity of cloud computing, achieving safe and efficient data exchange in cloud settings is a pressing issue that must be addressed. Furthermore, achieving both anonymity and traceability in the cloud for data exchange is a difficulty. This work focuses on providing anonymous data exchange and storage in the cloud for the same group with good security and efficiency. A unique traceable group data sharing strategy is developed to allow anonymous multiple users in public clouds by leveraging the key agreement and the group signature. On the one hand, group members can communicate anonymously with regard to the group signature, and on the other hand, group members can track the anonymous members, chat within the group, store and share for secure instant access and updates.
