BlindStep MPC kernel for privacy-preserving collaborative reasoning
BlindStep is a fixed-shape MPC-online kernel that provides simulation-based guarantees for bounded-slot aggregation between semi-honest parties.
RV2GC rebuilds garbling around fixed RISC-V instruction circuits
On nine benchmarks, ARM2GC-to-RV2GC runtime ratios ranged from 12.81 to 4,043, with public scheduling kept outside the circuits.
Paper cuts multi-party computation communication with compact secret sharing
Combining CRYPTO 2007 preprocessing with a modified ramp scheme yields constant amortized gate-evaluation communication under stated conditions.
Quantum protocols cut communication for equality, majority, and AND
Entanglement-assisted three-party equality uses about 1.633n qubits, versus at least 3n without it.
On the Complexity of Symmetric Boolean Functions in Multiparty Private Simultaneous Messages
Paper proves superlinear PSM lower bounds for symmetric Boolean functions and near-linear support-private upper bounds.
Robust and leakage-resilient device-independent oblivious transfer in MiniQCryp
Paper constructs device-independent oblivious transfer and bit commitment secure against quantum adversaries using untrusted devices.
Low-Rank Masking for Single-Server Matrix Multiplication
Researchers prove rank-r additive masks for outsourced matrix multiplication achieve maximal-correlation secrecy of at most q^-r, with a matching lower bound.
SEEK: Secure and Efficient Encrypted Keyword Search For Privacy-Preserving Messaging Protocols
Researchers propose SEEK, a homomorphic-encryption plus 2PC protocol for encrypted keyword search that hides keywords while detecting matches.
Distributed and Private Textual Data Synthesis from Embeddings
Researchers propose a distributed differentially private text synthesis method combining DP summaries and secure protocols, removing the need for a trusted curator.
