In order to solve the problem that most of the existing blockchain-based searchable encryption schemes only support exact keyword search and mutual distrust between the cloud server and the user, a searchable encryption scheme based on blockchain, that has functions such as file update dynamically, search results verification, fuzzy keyword search, and fair payment, is proposed. We use edit distance to generate the fuzzy keywords set. According to the un-modification characteristic of Ethereum blockchain and the security of the RSA accumulator, our scheme can verify the search results by the smart contract and realize the service-payment fairness between the user and the cloud server. The security analysis shows that the proposed scheme achieves non-adaptive semantic security. Performance analysis and experiment show that our scheme is efficient and meets the demand of search application in the cloud environment. INDEX TERMS Ethereum blockchain, fuzzy keyword search, fair payment, searchable encryption.

“…The suggested technique allows the server in DGHV Homomorphic encryption to provide an reversed encryption index structure with no involving query trapdoor to efficiency improve the search. [10] In cloud computing, the cipher text policy attribute based encryption (CPABE) analyzes the challenges faced in safe data sharing and developed encryption algorithm for it. Normally, the shared data files must have multilevel hierarchy characteristic, especially in military area.…”

Cloud Security is a technique of safeguarding applications, infrastructures and data involved in cloud computing. Cloud security uses a set of technologies, policies and controls to protect data and application from unauthorized access. RSA encryption and decryption algorithm is presented here for cloud security. The cloud can access the data only after receiving the user’s encrypted message using RSA algorithm. However, while transmitting the encrypted message more bandwidth is consumed as the message is transmitted over wireless channel. To minimize the bandwidth, the encrypted message is transmitted into a number of encoded bits and the cloud service provider can append the bits and recover the original message. The performance results for RSA algorithm and the RSA algorithm using Fountain Code are simulated. The results show that the energy, end-to-delay are minimized while using Fountain Code RSA algorithm. In addition, the packet loss ratio decrease and the packet delivery ratio increase.

“…However, PEKS often has much more computation overheads than SSE due to doing paring computations. There are more recent works for improving security [17,18], improving functionality [19,20], and improving performance [21] for the PEKS. Boneh et al showed that PEKS implies IBE [13].…”

Massive data are generated and collected by devices in the industrial Internet of Things. Data sources would encrypt the data and send them to the data center through the gateway. For some supervision purpose, the gateway needs to observe the encrypted data stream and label the suspicious data. Instead of decrypting ciphertext at the gateway, which is not efficient, this paper presents a Φ-searchable functional encryption scheme that supports inner product evaluations on encrypted data. Based on this scheme, an approach enabling various queries on the encrypted industrial data stream is proposed. The adaptive security of our proposed underlying functional encryption scheme can be proven under general subgroup decision assumptions, and our scheme has the smaller public key, the smaller secret key, and the smaller ciphertext size compared to the related schemes. In addition, the experimental results show that our proposed scheme is efficient. Especially for the gateway, querying on the encrypted data only needs less than 20ms, which is practical for industrial data stream auditing scenario.
