Privacy-preserving ciphertext-policy attribute-based search over encrypted data in cloud storage

Abstract

This thesis presents Privacy-Preserving Ciphertext-Policy Attribute-Based Searchable encryption schemes to achieve data privacy, keyword searchability, and fine-grained access control. The works related to this thesis address the issues with the existing related schemes like Data Authentication, Inefficient encryption and decryption, Inefficient traceability and revocation, Key-escrow problems, Prone to quantum attacks, and Lack of semantic search. The performance of all the proposed schemes was evaluated on a local machine.
