چکیده

The Industrial Internet of Things (IIoT) represents a variety of IoT applications in the industrial sector of economy and is heavily underpinned by computational capabilities of cloud computing to reduce the cost of on-demand services.‎ However, cloud computing does not protect the privacy of the outsourced data unless some form of encryption is applied.‎ Recently, some Certificateless Authenticated Encryption with Keyword Search (CLAEKS) schemes have been proposed.‎ However, it is known in the literature that the security of these schemes is proved based on a weak security model.‎ In this paper, we first provide a more powerful and realistic security model for CLAEKS schemes.‎ Then, we propose a new CLAEKS scheme and prove its security in the enhanced security model.‎ The comparison results show that the proposed CLAEKS scheme is the only existing searchable encryption scheme in the certificateless setting that is secure in the enhanced security model.‎
