“…In recent years, to address security concerns caused by various kinds of attacks, such as file-injection attack, Bost et al proposed a dynamic SSE scheme that ensures forward security for the leakage caused by the access pattern [11] and later gave several schemes achieving both forward and backward privacy [12]. In addition to the improvements in efficiency and security mentioned above, much work has been done to extend the functionality of the SSE schemes, including dynamic SSE that supports file additions and deletions [13,14], conjunctive SSE that enables users to search multiple keywords [15,16] and fuzzy SSE [17,18].…”

With the rapid development of wireless communication technology, the Internet of Things is playing an increasingly important role in our everyday. The amount of data generated by sensor devices is increasing as a large number of connectable devices are deployed in many fields, including the medical, agricultural, and industrial areas. Uploading data to the cloud solves the problem of data overhead but results in privacy issues. Therefore, the question of how to manage the privacy of uploading data and make it available to be interconnected between devices is a crucial issue. In this paper, we propose a scheme that supports real-time authentication with conjunctive keyword detection (RA-CKD), this scheme can realize the interconnection of encrypted data between devices while ensuring some measure of privacy for both encrypted data and detection tokens. Through authentication technology, connected devices can both authenticate each other's identity and prevent malicious adversaries from interfering with device interconnection. Finally, we prove that our scheme can resist inside keyword guessing attack through rigorous security reduction. The experiment shows that the efficiency of RA-CKD is good enough to be practical.

“…In the end, the storage server sends the retrieved ciphertexts to the recipient. After the concept of PEKS was put forward, various PEKS schemes and variants have been proposed [8][9][10][11][12][13][14][15][16][17][18][19]. In PEKS, the search tokens need to be conveyed over secure channels to the storage server.…”

Public key encryption with keyword search (PEKS) allows a user to make search on ciphertexts without disclosing the information of encrypted messages and keywords. In practice, cryptographic operations often occur on insecure devices or mobile devices. But, these devices face the risk of being lost or stolen. Therefore, the secret keys stored on these devices are likely to be exposed. To handle the key exposure problem in PEKS, the notion of key-updatable PEKS (KU-PEKS) was proposed recently. In KU-PEKS, the users' keys can be updated as the system runs. Nevertheless, the existing KU-PEKS framework has some weaknesses. Firstly, it can't update the keyword ciphertexts on the storage server without leaking keyword information. Secondly, it needs to send the search tokens to the storage server by secure channels. Thirdly, it does not consider the search token security. In this work, a new PEKS framework named key-updatable and ciphertext-sharable PEKS (KU-CS-PEKS) is devised. This novel framework effectively overcomes the weaknesses in KU-PEKS and has the ciphertext sharing function which is not supported by KU-PEKS. The security notions for KU-CS-PEKS are formally defined and then a concrete KU-CS-PEKS scheme is proposed. The security proofs demonstrate that the KU-CS-PEKS scheme guarantees both the keyword ciphertext privacy and the search token privacy. The experimental results and comparisons bear out that the proposed scheme is practicable.
