Extractor codes

Research output: Contribution to journalConference articlepeer-review


We define new error correcting codes based on extractors. We show that for certain choices of parameters these codes have better list decoding properties than are known for other codes, and are provably better than Reed-solomon codes. We further show that codes with strong list decoding properties are equivalent to slice extractors, a variant of extractors. We give an application of extractor codes to extracting many hardcore bits from a one-way function, using few auxiliary random bits. Finally, we show that explicit slice extractors for certain other parameters would yield optimal bipartite Ramsey graphs.
