Fine Grained Outsourced Data Puncturing in Cloud: Data Deletion (Paperback) (ISBN-13: 9798896320104)

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-even to those with access to secret keys.
