Explore a comprehensive presentation on statistical zaps and novel oblivious transfer protocols delivered at Eurocrypt 2020. Delve into the intricacies of statistical security in two-party protocols, interactive proof systems, and witness indistinguishability. Examine the concept of zaps as two-round public-coin witness-indistinguishable protocols and their application to oblivious transfer. Investigate the development of weakly secure statistical zaps and methods to amplify their security. Learn about statistical receiver-private oblivious transfer and the crucial role of statistical hash commitments. Gain insights into the three-round statistical receiver-private oblivious transfer protocol derived from statistical hash commitments, and understand how these commitments can be constructed from two-round oblivious transfer. Conclude with a summary of the key findings and their implications for cryptographic research.
