FINE GRAINED OUTSOURCED DATA PUNCTURING IN CLOUD: Data Deletion

<p>This book introduces a robust cryptographic approach that empowers data owners with complete control over their sensitive information. By leveraging advanced attribute-based encryption techniques it provides a systematic methodology for encrypting outsourcing and permanently deleting data. With a focus on user-defined deletion policies and puncture-based cipher text management this framework ensures that once deleted the data remains inaccessible&mdash;even to those with access to secret keys.</p>
