Authorized Keyword Search over Outsourced Encrypted Data in Cloud Environment

Project Code :TCMAPY1025

Objective

The objective is to introduce a novel expressive authorized keyword search scheme for encrypted data in cloud servers. The scheme supports multi-owner, multi-user scenarios, ensures semantic security against various attacks, introduces an interactive protocol without secure-channels, enables efficient user revocation and authentication, supports conjunctive keyword searches, and outperforms related works.

Abstract

This paper introduces an innovative approach to secure keyword search over encrypted cloud data using ciphertext-policy attribute-based encryption. It accommodates multiple data owners and users, ensuring generic and convenient access. The scheme guarantees semantic security against keyword attacks, employs an efficient interactive protocol, and utilizes bilinear-map accumulators for user and attribute revocation. It supports conjunctive keyword search, enabling simultaneous searches at minimal cost. The proposed system excels in performance compared to similar works. Overall, it offers enhanced data availability and accessibility while preserving secrecy, making it a robust solution for secure cloud-based keyword searches.

Keyword: conjunctive keyword search, searchable encryption, attribute-based encryption, user revocation, keyword guessing attack.
