A Multi-client Dynamic Searchable Symmetric Encryption System with Physical Deletion

Lecture Notes in Computer Science, 2018
Dynamic Searchable Symmetric Encryption (DSSE) provides a simple and fast storage as well as retrieval method for encrypted profiles which stored in cloud. However, due to the nature of the symmetric encryption algorithm, it allows only one client to access the data. To make the scheme more practical, this paper propose a multi client dynamic symmetric

Universally Composable Forward Secure Dynamic Searchable Symmetric Encryption

Proceedings of the 8th ACM on ASIA Public-Key Cryptography Workshop, 2021
Kurosawa et al. formulate a universally composable (UC) security definition of dynamic searchable symmetric encryption (DSSE). They also show (weak) equivalence between the UC and the game-based definition, and introduce a UC secure DSSE scheme (KSOY scheme).

Forward Secure Dynamic Searchable Symmetric Encryption with Lighter Storage

Proceedings of the 2020 4th International Conference on Cryptography, Security and Privacy, 2020
Users with limited computing and storage capabilities can access large amounts of data easily by uploading the database to cloud server. But this leads to security issues. Dynamic searchable encryption scheme is a solution, providing not only data privacy for users, but also the ability of searching for keywords on the ciphertext and inserting or ...

Dynamic Searchable Symmetric Encryption with Full Forward Privacy

2020 IEEE 5th International Conference on Signal and Image Processing (ICSIP), 2020
Many approaches address the problem of Searchable Symmetric Encryption (SSE), and in the last few years scholars introduced Dynamic SSE (DSSE) schemes in which a client is able to add, delete, and update documents along with performing searches over encrypted documents.

Dynamic Searchable Symmetric Encryption with Forward and Backward Privacy: A Survey

2019
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 not covered most recent advances on SSE technique.

Forward Secure Dynamic Searchable Symmetric Encryption with Efficient Updates

Proceedings of the 2017 ACM SIGSAC Conference on Computer and Communications Security, 2017
The recently proposed file-injection type attacks are highlighting the importance of forward security in dynamic searchable symmetric encryption (DSSE). Forward security enables to thwart those attacks by hiding the information about the newly added files matching a previous search query.

Multi-user Forward Secure Dynamic Searchable Symmetric Encryption

2018
Searchable Symmetric Encryption (SSE) makes it possible to privacy-preserving search over encrypted data stored on an untrusted server. Dynamic SSE schemes add the ability for the user to support secure update of encrypted data records. However, recent attacks show that update information can be exploited to recover the underlying values of ciphertexts.

Keyword-Search Interval-Query Dynamic Symmetric Searchable Encryption

2019
Searchable Symmetric Encryption (SSE) enables clients to securely store data on untrusted server while keeping the ability to search and update over the encrypted data efficiently. For practical purposes, we also need several additional properties to make our search function more versatile.

Secure, Efficient and Dynamic Data Search using Searchable Symmetric Encryption

2020 5th International Conference on Cloud Computing and Artificial Intelligence: Technologies and Applications (CloudTech), 2020
Fog computing, which works complementary to cloud computing, is being developed to overcome the issue of cloud computing such as latency in the cases where the data is to be retrieved immediately. But, along with solving the problem of latency, fog computing brings along with it different set of security issues than cloud computing.

Dynamic Symmetric Searchable Encryption from Constrained Functional Encryption

2016
Searchable symmetric encryption allows a party to encrypt data while maintaining the ability to partially search for over it. We present a scheme that balances efficiency, privacy, and the set of admissible operations: Our scheme searches in time logarithmic in the size of the word dictionary i.e., it is independent of the number of files, satisfies ...
