Certificateless conjunctive keyword search over encrypted data
摘要
Abstract
As the certificate-based searchable encryption schemes need to verify the data user's public key and manage certificates,and single keyword search always return huge volumes of irrelevant ciphertext.Therefore,by exploiting the identity encryption technique we propose a certificateless conjunctive keyword search over encrypted data scheme which can eliminate the key escrow problem and avoid the waste of bandwidth and computational resources.Rigorous security analysis proves that Our proposed scheme is secure against the off-line keyword guessing attack in the standard model.Moreover,the empirical experiment on real-world dataset demonstrates its efficiency and feasibility in practical scenarios.关键词
