“…Table 1 shows performance comparison between our scheme and literature [ 31 – 35 ]. The literature [ 31 ] supports multi-keyword search and security proof under the hard problem, but it does not support attribute-based encryption and revocation.

“…Table 2 shows efficiency comparison between the proposed scheme and the literature [ 31 – 35 ]. Since literature [ 32 – 35 ] do not support multi-keyword search, the proposed scheme and literature [ 31 ] have requirements for the number of keywords in the encryption, token generation, and search phases. For comparison, we consider that the quantity of encrypted keywords is equivalent to the quantity of search keywords, that is r = d .…”

“…In Fig 2(A), 2(B) and 2(C) are time charts for running encryption algorithm as the number of attributes increases when keyword set contains 10, 20, and 30 keywords, respectively. Since literature [ 32 – 35 ] do not support multi-keyword search function, the proposed scheme is mainly compared with literature [ 31 ]. From the Fig 2 , we can see that in the encryption phase, the calculation speed of our scheme is slower than literature [ 33 ], faster than literature [ 31 , 32 , 34 , 35 ].…”

We propose an attribute-based encryption scheme with multi-keyword search and supporting attribute revocation in cloud storage environment, in which binary attributes and AND-gate access policy are used. Our proposal enjoys several advantages. Firstly, multi-keyword search is available, and only when a data user's attribute set satisfies access policy in keyword index, and keyword token generated by data user matches index successfully, then data user can obtain ciphertext containing keywords. In this way, more accurate keyword search is achievable. Secondly, the search privacy of data user is protected owing to cloud servers cannot obtain any knowledge of keywords which data user is interested in. Meanwhile, the ciphertext is able to be decrypted when data user's attribute set satisfies access policy specified in the ciphertext, which can both improve security of encryption and achieve secure fine-grained access control. Thirdly, the proposed scheme supports attribute revocation, in our scheme when a data user's attribute is revoked, the version number of attribute, non-revoked data users' secret keys and related ciphertexts will be updated, such that data user whose attribute is revoked does not decrypt updated ciphertext anymore. In addition, based on the assumption of decisional linear (DL) and decisional Diffie-Hellman (DDH), our scheme is proved to be secure against selectively chosen-keyword attacks and selectively chosen-plaintext attacks respectively, and it also ensures token privacy security.

In attribute-based searchable encryption (ABSE) scheme, data owners can encrypt their data with access policy for security consideration, and encrypt keywords to obtain keyword index for privacy keyword search, and data users can search interesting keyword on keyword indexes by keyword search trapdoor. However, many existing searchable encryption schemes only support single keyword search and most of the existing attribute-based encryption (ABE) schemes have high computational costs at user client. These problems significantly limit the application of attribute-based searchable encryption schemes in practice. In this paper, we propose a verifiable and multi-keyword searchable attribute-based encryption (VMKS-ABE) scheme for cloud storage, in our new scheme, multi-keyword can be searched and the search privacy is protected. That is, the cloud server can search the multi-keyword with keyword search trapdoor but it does not know any information about the keywords searched. In the proposed scheme, many computing tasks are outsourced to the cloud proxy server, which greatly reduces the computing burden at the user client. Besides, the scheme also supports the verification of the correctness of the outsourced private key. The proposed scheme is proved secure that the keyword index is indistinguishable under the adaptive keyword attacks in the general group model, and the ciphertext is selective secure under selective plaintext attacks in the random oracle model. The security and experimental results show that our scheme is suitable for practicability. INDEX TERMS Attribute-based encryption, verifiable outsourcing, multi-keyword search, adaptive security.
