Multi-keyword search over encrypted data with user revocation
摘要
Abstract
A multi-keyword search over encrypted data was proposecl with file-level access authorization and data user revocation scheme through employing ciphertext-policy attribute-based encryption (CP-ABE).The scheme supports file-level access authorization in the multi-owner multi-user settings,which means that data users could only gain the authorized files encrypted by different data owners with different keys.Moreover,the scheme could achieve data user revocation.Formal security analysis shows that the proposed scheme could resist the chosen keyword attack in random oracle.Moreover,the experimental study over real-world dataset demonstrates its efficiency and feasibility in practice.关键词
