Supporting Secure Dynamic Alert Zones Using Searchable Encryption and Graph Embedding [PDF]
arXiv, 2023 Location-based alerts have gained increasing popularity in recent years, whether in the context of healthcare (e.g., COVID-19 contact tracing), marketing (e.g., location-based advertising), or public safety. However, serious privacy concerns arise when location data are used in clear in the process.

Accelerating Forward and Backward Private Searchable Encryption Using Trusted Execution [PDF]
arXiv, 2020 Searchable encryption (SE) is one of the key enablers for building encrypted databases. It allows a cloud server to search over encrypted data without decryption. Dynamic SE additionally includes data addition and deletion operations to enrich the functions of encrypted databases.

Dynamic Searchable Symmetric Encryption Schemes Supporting Range Queries with Forward/Backward Privacy [PDF]
arXiv, 2019 Dynamic searchable symmetric encryption (DSSE) is a useful cryptographic tool in encrypted cloud storage. However, it has been reported that DSSE usually suffers from file-injection attacks and content leak of deleted documents. To mitigate these attacks, forward privacy and backward privacy have been proposed.

OBI: a multi-path oblivious RAM for forward-and-backward-secure searchable encryption
Network and Distributed System Security Symposium, 2023 —Dynamic searchable encryption (DSE) is a user-cloud protocol for searching over outsourced encrypted data. Many current DSE schemes resort to oblivious RAMs (ORAM) to achieve forward privacy and backward privacy, which is a concept to describe security ...

Forward Private Searchable Symmetric Encryption with Optimized I/O Efficiency [PDF]
arXiv, 2017 Recently, several practical attacks raised serious concerns over the security of searchable encryption. The attacks have brought emphasis on forward privacy, which is the key concept behind solutions to the adaptive leakage-exploiting attacks, and will very likely to become mandatory in the design of new searchable encryption schemes.

Password-authenticated searchable encryption [PDF]
International Journal of Information Security, 2020 AbstractWe introducePassword Authenticated Searchable Encryption (PASE), a novel searchable encryption scheme where a single human-memorizable password can be used to outsource (encrypted) data with associated keywords to a group of servers and later retrieve this data through the encrypted keyword search procedure.

Dynamic Local Searchable Symmetric Encryption [PDF]
, 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.

CP-ABSE: A Ciphertext-Policy Attribute-Based Searchable Encryption Scheme
IEEE Access, 2019 Searchable encryption provides an effective mechanism that achieves secure search over encrypted data. A popular application model of searchable encryption is that a data owner stores encrypted data to a server and the server can effectively perform ...
