We initiate the study of error correcting codes over the multi-party adversarial broadcast channel. Specifically, we consider the classic information dissemination problem where $n$ parties, each holding an input bit, wish to know each other's input. For this, they communicate in rounds, where, in each round, one designated party sends ... more >>>
We show how to convert any circuit of poly-logarithmic depth and polynomial size into a functionally equivalent circuit of polynomial size (and polynomial depth) that is resilient to adversarial short-circuit errors. Specifically, the resulting circuit computes the same function even if up to $\epsilon d$ gates on every root-to-leaf path ... more >>>
An oblivious bit-fixing source is a distribution over $\{0,1\}^n$, where $k$ bits are uniform and independent and the rest $n-k$ are fixed a priori to some constant value. Extracting (close to) true randomness from an oblivious bit-fixing source has been studied since the 1980s, with applications in cryptography and complexity ... more >>>
