TL;DR
A new private telemetry system for computing t - heavy hitters in the STAR and POPSTAR model that efficiently adapts multi-dealer secret sharing to the STAR/POPSTAR model and introduces a novel oblivious secret-share sampling protocol to ensure security against a colluding Aggregation Server.
This work proposes a fault-tolerant PIR protocol based on a newly designed (t,p)-threshold distributed point function (FT-DPF), and proves that the stateless protocol guarantees (t−1)-computational privacy under the semi-honest model.
Dynamic Searchable Symmetric Encryption (DSSE) enables efficient searches over encrypted data but often suffers from search pattern leakage, allowing adversaries to infer sensitive information. While schemes using Oblivious RAM (ORAM) mitigate leakage, their high cost hinders large-scale applications. Dory adopts a mul...
The augmented multi-party shuffle DP (AMP-SDP) model is proposed, which re-architects the data pipeline with a lightweight, versatile secret-shared intermediary layer that decentralizes trust while minimizing online communication costs and provides structural security hardening against both shuffler compromise and user-sid...
This work introduces a new PSU protocol that is simple, efficient, and secure against known during-execution leakage and hashing-related leakage without relying on Cuckoo Hashing, and achieves linear complexity.
The results guarantee security against fixed-target forgery under a single-signature-exposure model under the assumption of a finite supply of quadratic-stabilizer public-key states over an odd-prime field.
