“…Many researchers have designed blockchain-aided IoT systems in order to improve the performance of traditional IoT architecture. Rahulamathavan et al combined the merits of attribute-based encryption (ABE) [9][10][11] and blockchain to improve the privacy of IoT systems. 12 They also proved that the calculation cost is acceptable on IoT terminal devices.…”

The developments of Narrow Band Internet of Things have attracted much attention from both academia and industry nowadays. While Narrow Band Internet of Things is gradually designed for commercial applications, it also confronts with several security concerns such as identification and privacy. Blockchain technique is equipped with authentication, auditing, and accountability, and thus it can serve as a promising tool for providing secure data communication on the network. To enhance the security level and achieve reliable data authentication and accountability for Narrow Band Internet of Things system, in this article, we combine the merits of blockchain technique and propose a blockchain-based architecture for Narrow Band Internet of Things. The presented architecture consists of three layers which are sensing layer, transport layer, and transaction layer. We describe the interaction processes between each layer in detail and construct the algorithms which are used to conduct data authentication and blockchain generation. By evaluation, our scheme is demonstrated to obtain favorable performances in terms of privacy, authentication, accountability, and efficiency, which makes it an appropriate method to be applied for secure data communication in Narrow Band Internet of Things systems.

“…Cloud computing offers a virtualized resource pool that uses distributed storage, where the immense data can be accessed with virtual applications over the internet on user demand. However, the knowledge that the cloud server is many times regarded as untrusted raises concerns by users [4] [5]. It would be difficult for users to consider storing data that is sensitive to the cloud server.…”

Cloud computing provides a broad range of services like operating systems, hardware, software and resources. Availability of these services encourages data owners to outsource their intensive computations and massive data to the cloud. However, considering the untrusted nature of cloud server, it is essential to encrypt the data before outsourcing it to the cloud. Unfortunately, this leads to a challenge when it comes to providing search functionality for encrypted data located in the cloud. To address this challenge, this paper presents a public key encryption with equality test for heterogeneous systems (PKE-ET-HS). The PKE-ET-HS scheme simulates certificateless public encryption with equality test (CLE-ET) with the identity-based encryption with equality test (IBE-ET). This scheme provides the authorized cloud server the right to actuate the equivalence of two messages having their encryptions performed under heterogeneous systems. Basing on the random oracle model, we construct the security of our proposed scheme under the bilinear Diffie-Hellman (BDH) assumption. Eventually, we evaluate the size of storage, computation complexities, and properties with other related works and illustrations indicate good performance from our scheme.

“…The data will be stored in the cloud in encrypted form and will not be accessible to any third party as long as the original key is not exposed. Hong and Sun 32 proposed a key separation ABPRE scheme is for the IoT scenario. By using attribute‐based encryption on encrypted data and adopting a key insulation mechanism to provide forward security for users' reencryption keys and private keys, safe and fine‐grained data sharing is achieved, and the security level during data reencryption is improved .…”

In recent years, the Internet of things (IoT) equipment has grown rapidly, and the scale of the IoT has also expanded. The IoT is deployed in the system in a centralized manner. At the same time that massive data has put a certain amount of pressure on the storage, the open network environment has not fully protected the privacy of the IoT data, which has become one of the important factors restricting the development of the IoT. Blockchain is a point‐to‐point distributed ledger technology based on cryptographic algorithms. The characteristics of decentralization, tamper resistance, anonymity, and public verifiability can alleviate data security issues in IoT. Ring signature and proxy reencryption are common encryption technologies in the field of privacy protection. Therefore, this article combines blockchain technology with ring signature and proxy reencryption to propose a privacy protection solution for the IoT. Through this solution, the data authorized for sharing in the IoT is transmitted in the system in the form of ciphertext, the identity information of the data sender is protected, and the distributed ledger eases the pressure of mass data storage on a centralized server. The correctness and safety of the proposed scheme are also analyzed.
