Coding-Based Hybrid Post-Quantum Cryptosystem for Non-Uniform Information
Saar Tarnopolsky, Alejandro Cohen
We introduce for non-uniform messages a novel hybrid universal network coding cryptosystem (NU-HUNCC) in the finite blocklength regime that provides Post-Quantum (PQ) security at h…
Optimal Computational Secret Sharing
Igor L. Aureliano, Alejandro Cohen, Rafael G. L. D'Oliveira
In -threshold secret sharing, a secret is distributed among participants such that any subset of size can recover , while any subset of size or fewer l…
A Monotone Circuit Construction for Individually-Secure Multi-Secret Sharing
Cailyn Bass, Alejandro Cohen, Rafael G. L. D'Oliveira +1
In this work, we introduce a new technique for taking a single-secret sharing scheme with a general access structure and transforming it into an individually secure multi-secret sh…
Error Correction Capabilities of Non-Linear Cryptographic Hash Functions
Alejandro Cohen, Rafael G. L. D'Oliveira
Linear hashes are known to possess error-correcting capabilities. However, in most applications, non-linear hashes with pseudorandom outputs are utilized instead. It has also been…
