Fault-tolerant Verifiable Dynamic SSE with Forward and Backward Privacy

IACR Communications in Cryptology
Dynamic Searchable Symmetric Encryption (DSSE) allows users to securely outsource their data to cloud servers while enabling efficient searches and updates. The verifiability property of a DSSE construction ensures that users do not accept incorrect search results from a malicious server while the fault-tolerance property guarantees the ...

Searchable Encryption for Conjunctive Queries with Extended Forward and Backward Privacy

Proceedings on Privacy Enhancing Technologies
Recent developments in the field of Dynamic Searchable Symmetric Encryption (DSSE) with forward and backward privacy have attracted much attention from both research and industrial communities. However, most DSSE schemes with forward and backward privacy schemes only support single keyword queries, which impedes its prevalence in practice.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...
