Vehicular Ad-hoc networks (VANETs) during the communication process, nodes are always varying and the process is always under security threats like Sybil attacks, masquerading attacks, etc. In order to reduce the probability of these attacks and to regulate traffic flow in the network, a software-defined network (SDN) is used. The SDN is used for implementing protocols like OpenFlow and reducing the routing load in the network, but it doesn’t provide a high level of security to the network, hence protocols like encryption, hashing, etc. are applied to the VANET. In the paper, SDN based blockchain-inspired algorithm is implemented, which coordinates network traffic and improves the overall security of the network. Security analysis of the proposed algorithm shows that the combination of blockchain with encrypted SDN is removing more than 95% of the network attacks as compared to its non-blockchain counterparts.

“…However, all of the abovementioned verifiable outsourcing schemes meet the CPA security requirements. A verifiable hidden policy CP-ABE with a decryption testing scheme (VHPDT) was proposed by Zhao et al [30], which is CCA-secure. Meanwhile, the VHPDT scheme introduces a predetection algorithm to increase the efficiency of the decryption.…”

Cloud storage is a popular model of the application in various fields, and the security of storage data and access permission have been widely considered. Attribute-based encryption (ABE) provides fine-grained user access control and ensures data confidentiality. However, current ABE access control schemes rely on trusted cloud servers and provide a low level of security. To solve these problems of traditional encryption schemes, we propose a blockchain-based and ABE cloud storage data access control scheme. In this article, blockchain and smart contract technology are the core elements to ensure data integrity and build a decentralized verification method for outsourcing results. This application can minimize the reliance on servers in the cloud environment. Based on the ciphertext-policy ABE algorithm, the proposed scheme supports a hidden access policy to avoid the risk of privacy leakage. In addition, we adopt outsourcing technology and predetected decryption algorithms to reduce the computational overhead of local and outsourced servers. Security analysis and performance evaluation show that our proposed scheme has high computational efficiency and satisfies the condition of indistinguishability under the chosen-ciphertext attacks.

“…CP‐ABE schemes 7,35 were proposed to provide fine‐grained access control over encrypted data, and CP‐ABSE schemes were proposed to provide both fine‐grained access control and keyword search, simultaneously. Zheng et al 18 designed a CP‐ABSE scheme enabling data owners to give fine‐grained search permissions.…”

“…As shown in Figure 1, in a cloud‐based IoT environment, data files are gathered by several smart devices and outsourced to a cloud service provider, and data users can obtain data of interest from the cloud. However, as the cloud service provider is not assumed to be trustworthy, 5–7 to provide the data confidentiality, encrypting the data before outsourcing is necessary. But unfortunately, searching over the encrypted data is a challenging task considering the current technologies.…”

As more data from Internet of Things (IoT) devices is outsourced to cloud service providers, the need for secure and efficient fine‐grained access control and data retrieving mechanisms will be increasingly pressing. Attribute‐based keyword search (ABKS) is a promising tool to provide the required infrastructures. However, most of the existing ABKS schemes suffer from expensive computational overhead on the user side. This feature makes such schemes unsuitable for IoT applications as IoT devices usually have limited computational resources. To address this problem, we design a lightweight ABKS scheme called LW‐ABKS. In our scheme, by performing a constant number of efficient computational operations, a data owner can generate a searchable ciphertext. Indeed, in generating a searchable ciphertext, the number of operations performed by data owners modeling IoT devices does not depend on the number of attributes in the access control policy. Moreover, in LW‐ABKS, an authorized data user can retrieve the outsourced data files by performing very lightweight computational operations. We also provide security definitions for the new primitive and prove its security in the standard model and under the hardness assumption of the discrete logarithm and the decisional bilinear Diffie‐Hellman problems.
