Searchable Symmetric Encryption (SSE) has emerged as a promising tool for facilitating efficient query processing over encrypted data stored in un-trusted cloud servers. Several techniques have been adopted to enhance the efficiency and security ...$\mathsf{}$$\mathsf{}$$\mathsf{}$

In the last decade, the smart grid has utilized many modern technologies and applications compared with the conventional grid. Cloud computing offers numerous managed services and storage solutions for smart grid data. To balance security, privacy,...

Searchable symmetric encryption (SSE) enables the client to outsource its encrypted database to the untrusted server, while maintaining the ability to efficiently search over it. However, most of the existing solutions focus mainly on exact ...

• We propose a dynamic multi-client fuzzy keyword search SSE scheme named MUFKS by integrating Intel SGX and multi-client SSE. Specifically, the client generates the corresponding trapdoors of fuzzy set with the aid of Intel SGX, which ...

Searchable symmetric encryption (SSE) allows a client to search over encrypted data. To address the real threat of key compromise in practice, this work initiates the study of key rotation for SSE and introduces the notion of updatable SSE (USSE)...

Searchable symmetric encryption (SSE) has recently been under the spotlight in a cloud data storage system due to its high efficiency. SSE allows a client to outsource his private data while maintaining data searchability. To ensure the ...

Boolean Searchable Symmetric Encryption (BSSE) enables users to perform retrieval operations on the encrypted data while supporting complex query capabilities. This paper focuses on addressing the storage overhead and privacy concerns associated ...

Dynamic multi-user searchable symmetric encryption (DMUSSE) enables the data owner to dynamically outsource encrypted database to the cloud server and selectively share the search capability with data users. However, inter-user state ...

With the continuous advancement of cloud computing technology, massive amounts of heterogeneous data are being outsourced to cloud servers. Dynamic searchable symmetric encryption (DSSE) is widely used for dynamically updating and ...

Recent years have witnessed the development and adoption of blockchain technology in intelligent transportation systems (ITS) because of its authenticity and traceability. However, increasing ITS devices impose grand challenges in ...

Searchable symmetric encryption (SSE) is a research hotspot in applied cryptography, with the purpose of protecting outsourced data while enabling querying of encrypted data. However, the majority of current research focuses on the scenario in ...

Cloud computing is now being used by more and more enterprises and individuals. To protect the privacy of outsourced data in the cloud, the searchable symmetric encryption is adopted. However, verifying search results to detect whether there is ...

The integration of Internet of Things (IoT) and cloud computing is transforming traditional healthcare systems into cloud-assisted e-healthcare systems. In a cloud-assisted e-healthcare system, patients can upload their personal health information ...

A searchable symmetric encryption (SSE) scheme enables a client to store data on an untrusted server while supporting keyword searches in a secure manner.

This work presents a new experiment defining indistinguishability for searchable symmetric encryption to include security against published practical attacks. The proposed experiment allows the adversaries to use their prior knowledge about the ...$$

We provide a new definitional framework capturing the multi-user security of encryption schemes and pseudorandom functions in the face of adversaries that can adaptively compromise users’ keys. We provide a sequence of results establishing the ...

Searchable symmetric encryption (SSE) has been proposed that enables the clients to outsource their private encrypted data onto the cloud server and later the data can be searched with limited information leakage. However, existing surveys have ...

Searchable symmetric encryption (SSE) for multi-owner model draws much attention as it enables data users to perform searches over encrypted cloud data outsourced by data owners. However, implementing secure and precise query, efficient search and ...

This paper concerns the fundamental problem of processing conjunctive keyword queries over an outsourced data table on untrusted public clouds in a privacy-preserving manner. The data table can be properly implemented with tree-based searchable ...

Nowadays, fast growing number of users and business are motivated to outsource their private data to public cloud servers. Taking into consideration security issues, private data should be encrypted before being outsourced to remote servers, though this ...

Searchable symmetric encryption (SSE) allows a data owner to outsource his encrypted data to a cloud server while retaining the ability to perform keyword search over encrypted data. The security guarantees of existing SSE schemes require that the ...
