Low Error Efficient Computational Extractors in the CRS Model

Explore a presentation on low error efficient computational extractors in the CRS model from Eurocrypt 2020. Delve into weak sources, randomness extractors, and two-source extractors with negligible error. Examine computational 2-source extractors and non-malleable extractors, including their construction and proof intuition. Learn how to convert non-malleable extractors with high entropy to 2-extractors with low entropy. Conclude with open problems in the field of cryptographic extractors.
