Abstract

Cloud computing has revolutionized data management, offering scalability and efficiency. However, it also presents significant security challenges, particularly in data deletion. Traditional deletion methods often leave residual data that can be recovered, increasing the risk of unauthorized access. Ensuring complete and irreversible data disposal is critical for maintaining data security and regulatory compliance. This research investigates crypto-shredding, a technique that enhances data security by destroying encryption keys, rendering the associated data permanently inaccessible. The study focuses on the design, implementation, and evaluation of crypto-shredding techniques within cloud environments, comparing their effectiveness to conventional deletion methods. A structured framework for integrating crypto-shredding into cloud architectures is proposed, ensuring compliance with data protection regulations such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA). The study also explores the role of user authentication mechanisms and content discovery techniques in verifying that deleted files leave no recoverable traces in active storage or archives. Extensive testing and performance analysis will assess the feasibility and reliability of crypto-shredding as a secure data disposal method. The findings of this research aim to strengthen cloud security frameworks, mitigate the risks of data breaches, and contribute to the advancement of secure data management practices in cloud computing.
