Any dd-regular graph on nn vertices with spectral expansion λλ satisfying n=Ω(d3log(d)/λ)n=Ω(d3log(d)/λ) yields a O(λ3/2d)O(λ3/2d)-non-malleable code in the split-state model.

Our proofs are based on a new search-to-decision reduction for expander-based functions. This extends a previous reduction of the first author (STOC 2012) which was applicable for the special case of ...

Threshold secret sharing is a protocol that allows a dealer to share a secret among nn players so that any coalition of tt players learns nothing about the secret, but any t+1t+1 players can reconstru...

We propose constructing provable collision resistant hash
functions from expander graphs. As examples, we investigate two specific
families of optimal expander graphs for provable hash function cons...
