A secure data dynamics and public auditing scheme for cloud storage

Cloud computing is an evolving technology that provides data storage and highly fast computing services at very low cost. Data stored in the cloud is managed by cloud service providers, raising concerns about authenticity, reliability, and integrity. Unauthorized users may misappropriate or alter data. This paper proposes a secure public auditing scheme employing a Third Party Auditor (TPA) to authenticate the privacy, reliability, and integrity of data stored in the cloud. The proposed scheme uses AES-256 for encryption, SHA-512 for integrity verification, and RSA-15360 for public key encryption, and supports data dynamics operations including insertion, deletion, and modification.
