Enabling Fast Public Auditing and Data Dynamics in Cloud Services

This paper addresses the challenge of efficiently supporting data dynamics in public auditing for encrypted cloud storage. Identifying cost limitations in existing schemes, we introduce a novel auditing protocol that achieves orders of magnitude faster data dynamics operations. Our challenge-response protocol significantly reduces the computation cost for Third-Party Auditors, enhancing verification speed. Through rigorous performance and security analyses, our proposed scheme demonstrates minimal computation costs while ensuring data integrity and privacy in an untrusted cloud environment. This research contributes a highly efficient solution, surpassing previous methods in speed and maintaining fundamental principles of data security in the cloud.
