Abstract:

Cloud computing involves delivering computing services like servers, databases, storage, and networking over the Internet. Cloud service providers (CSPs) are responsible for overseeing the data stored on the cloud. Users benefit from time and memory savings when they utilize cloud storage. However, once data is uploaded to the cloud, it becomes inaccessible to the user. Hence, safeguarding user data in the cloud necessitates tackling several critical security challenges. In our study, we employed a Third-Party Auditor (TPA) to develop a secure auditing system. We utilized the Secure Hash Algorithm (SHA-2) for computing the message digest and applied the Advanced Encryption Standard (AES-256) for encrypting user data. The system operates by launching a Windows Server instance on the Amazon EC2 cloud platform. The results demonstrate that our proposed method is secure and requires a significant amount of time to verify the accuracy of files stored in the cloud.
