Verifiable Attribute-based Keyword Search Encryption with Attribute Revocation for Electronic Health Record System
2020
International Journal of Network Security
Considering the security requirements of electronic health record (EHR) system, we propose a ciphertextpolicy attribute-based encryption scheme, which can support data retrieval, result verification and attribute revocation. In the proposed scheme, we make use of the BLS signature technique to achieve result verification for attribute-based keyword search encryption. In addition, key encrypting key (KEK) tree and re-encryption are utilized to achieve efficient attribute revocation. By giving
