Abstract

To minimize costs associated with software maintenance, hardware infrastructure, and secure communication, many organizations and data owners are increasingly opting for cloud storage solutions. However, ensuring the integrity and security of data stored on cloud servers (CS) remains a significant concern. Traditional methods typically use data encryption and decryption to safeguard data integrity, requiring DOs to download, decrypt, audit, and then re-encrypt data before re-uploading it to the CS. This approach is computationally intensive and introduces vulnerabilities, such as data leakage risks, particularly if encryption keys are compromised or data is transferred over insecure channels. While several methods have been proposed to enhance data integrityand availability on cloud platforms, few comprehensively address user data privacy and security, especially in group settings where user revocation is needed. Additionally, current solutions often fail to mitigate risks to sensitive data during the audit process itself. This paper proposes a novel framework designed to protect user identity and data privacy during public auditing of cloud-stored data. By building on and improving existing methods, this framework provides enhanced data confidentiality and integrity while reducing computational and communication overhead. It is also adaptable to various cloud storage models, including Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), thus offering a versatile and practical solution for secure cloud environments.
