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…
An Efficient Hybrid Key Exchange Mechanism
Benjamin D. Kim, Vipindev Adat Vasudevan, Alejandro Cohen +3
We present \textsc{CHOKE}, a novel code-based hybrid key-encapsulation mechanism (KEM) designed to securely and efficiently transmit multiple session keys simultaneously. By encodi…
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…
Cryptanalysis via Machine Learning Based Information Theoretic Metrics
Benjamin D. Kim, Vipindev Adat Vasudevan, Rafael G. L. D'Oliveira +3
The fields of machine learning (ML) and cryptanalysis share an interestingly common objective of creating a function, based on a given set of inputs and outputs. However, the appro…
