Searchable Symmetric Encryption with Forward Search Privacy [PDF]
IEEE Transactions on Dependable and Secure Computing, 2021 Searchable symmetric encryption (SSE) has been widely applied in the encrypted database for queries in practice. Although SSE is powerful and feature-rich, it is always plagued by information leaks. Some recent attacks point out that forward privacy which disallows leakage from update operations, now becomes a basic requirement for any newly designed

Dynamic multi-keyword searchable encryption scheme
网络与信息安全学报, 2023 Users of cloud storage often outsource their data to cloud servers to save local storage resources.However, cloud storage data is out of the user’s physical control, which may lead to malicious theft or disclosure of private data on cloud.At present ...

The Locality of Searchable Symmetric Encryption [PDF]
, 2014 This paper proves a lower bound on the trade-off between server storage size and the locality of memory accesses in searchable symmetric encryption (SSE). Namely, when encrypting an index of N identifier/keyword pairs, the encrypted index must have size ω(N) or the scheme must perform searching with ω(1) non-contiguous reads to memory or the scheme ...

Dynamic Local Searchable Symmetric Encryption
, 2022 In this article, we tackle for the first time the problem of dynamic memory-efficient Searchable Symmetric Encryption (SSE). In the term "memory-efficient" SSE, we encompass both the goals of local SSE, and page-efficient SSE. The centerpiece of our approach is a novel connection between those two goals.

Searchable Symmetric Encryption
, 2023 AbstractSearchable symmetric encryption allows operating on encrypted data, particularly keyword-based search on documents and range-based search on spatial data. Various methods can be used in Searchable symmetric encryption, such as order-preserving or fully homomorphic encryption, for different levels of information leakage.
