Certificateless Multi -Replica Data Integrity Auditing for Shared Data in Cloud-Based Disaster Resilience Systems
Deepansh Kumar, Aaryaman Giri, Akhilesh Kumar Srivastava · 2024
In the context of Disaster Resilience Systems(DRS), where data integrity and availability are paramount, cloud storage plays a crucial role. However, security concerns persist, necessitating innovative approaches. In the context of the DRS framework, this paper presents a novel Certificateless Multi-Replica Public Auditing Scheme designed for shared data in cloud storage. The suggested solution handles security concerns without adding to the workload associated with key escrow problems or certificate administration. This technique allows for secure user withdrawal from user group. It is shown that this scheme is secure against three various adversaries, defined in this paper, under common hardness assumptions by a thorough security study. Performance evaluations shows that this scheme is efficient and is also practical, positioning it as a viable solution for ensuring data integrity and availability in DRS.
