Practical Non-Interactive Searchable Encryption with Forward and Backward Privacy

Shi-Feng Sun, Ron Steinfeld, Shangqi Lai, Xingliang Yuan, Amin Sakzad, Joseph Liu, ‪Surya Nepal‬, Dawu Gu
2021 Proceedings 2021 Network and Distributed System Security Symposium   unpublished
At last, we implement our scheme and compare it with the most efficient Type-II backward-private scheme to date (Demertzis et al., NDSS 2020).  ...  In Dynamic Symmetric Searchable Encryption (DSSE), forward privacy ensures that previous search queries cannot be associated with future updates, while backward privacy guarantees that subsequent search  ...  In addition, most of existing backward and forward-private SSE schemes support only restricted types of queries, so constructing practical SSE schemes with support for strong security as well as rich queries  ...

Enclave Computing Paradigm: Hardware-assisted Security Architectures & Applications

Franz Ferdinand Peter Brasser
Preventing side-channel leakage from enclaves in a universal and efficient way is a non-trivial problem. Nevertheless, these deployed TEE solutions enable various novel applications.  ...  The TEE solutions developed by industry and deployed in today's systems follow distinct design approaches and come with various limitations.  ...  Thus, designing an efficient searchable encryption scheme with minimal leakage on the queried ranges remains an open challenge.  ...
