On the Insecurity of Parallel Repetition for Leakage Resilience
A fundamental question in leakage-resilient cryptography is: can leakage resilience always be amplified by parallel repetition? It is natural to expect that if we have a leakage-r...

Adaptively Secure Feldman VSS and Applications to Universally-Composable Threshold Cryptography
We propose the first distributed discrete-log key generation (DLKG) protocol from scratch which is adaptively-secure in the non-erasure model, and at the same time completely avoi...
