Secret sharing with additive access structures from correlated random variables
David Miller, Rémi A. Chou
We generalize secret-sharing models that rely on correlated randomness and public communication, originally designed for a fixed access structure, to support a sequence of dynamic…
Distributed Batch Matrix Multiplication: Trade-Offs in Download Rate, Randomness, and Privacy
Amirhosein Morteza, Remi A. Chou
We study the trade-off between communication rate and privacy for distributed batch matrix multiplication of two independent sequences of matrices and wit…
Secret Sharing Schemes from Correlated Random Variables and Rate-Limited Public Communication
Rumia Sultana, Remi A. Chou
A dealer aims to share a secret with participants so that only predefined subsets can reconstruct it, while others learn nothing. The dealer and participants access correlated rand…
Dual-Source SPIR over a noiseless MAC without Data Replication or Shared Randomness
Remi A. Chou
Information-theoretically secure Symmetric Private Information Retrieval (SPIR) is known to be infeasible over noiseless channels with a single server. Known solutions to overcome…
