Random Oracle Models and Combiners - Crypto 2023 Session 2

YouTube·Cryptography

Explore the cutting-edge developments in Individual Cryptography presented at Crypto 2023 in this session chaired by Jonathan Katz. Delve into topics such as account sharing, partial reconstruction of shared secrets, massive parallel computations, and distributed adversaries. Examine the MPC-Oracle concept, formal models with extractors, and the Proof of Individual Knowledge (PIK) definition. Learn about the procedure scratch(S, Z, W), completeness, soundness, and extractor efficiency. Investigate multi-property combiners, Cryptophia's Short Combiner Modelling, Random Oracle Combiners, and real-world hash functions. Gain insights into single-stage game considerations and explore open questions in the field of cryptography.
