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 ...

Storage Efficient Substring Searchable Symmetric Encryption [PDF]
Proceedings of the 6th International Workshop on Security in Cloud Computing, 2018 We address the problem of substring searchable encryption. A single user produces a big stream of data and later on wants to learn the positions in the string that some patterns occur. Although current techniques exploit auxiliary data structures to achieve efficient substring search on the server side, the cost at the user side may be prohibitive.

Exploiting Update Leakage in Searchable Symmetric Encryption
Proceedings of the Fourteenth ACM Conference on Data and Application Security and PrivacyDynamic Searchable Symmetric Encryption (DSSE) provides efficient techniques for securely searching and updating an encrypted database. However, efficient DSSE schemes leak some sensitive information to the server. Recent works have implemented forward and backward privacy as security properties to reduce the amount of information leaked during update ...

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 ...

Shared and Searchable Encrypted Data for Untrusted Servers [PDF]
, 2008 Current security mechanisms pose a risk for organisations that outsource their data management to untrusted servers. Encrypting and decrypting sensitive data at the client side is the normal approach in this situation but has high communication and ...
