Second-Order Expansion of Privacy Amplification Under f-Divergence Criteria

Mario Berta, Hao-Chung Cheng, Marco Tomamichel

We derive the second-order asymptotics of randomness extraction from memoryless sources with side information under security criteria based on a broad class of Csiszàr f-divergence…

Exponents for Shared Randomness-Assisted Channel Simulation

Aadil Oufkir, Michael X. Cao, Hao-Chung Cheng +1

We determine the exact error and strong converse exponents of shared randomness-assisted channel simulation in worst case total-variation distance. Namely, we find that these expon…
