Overview
Explore a talk from Asiacrypt 2016 on shuffle arguments secure in the generic model. Delve into e-voting motivation, simple mix-nets, and CRS-based shuffle arguments. Examine zero-knowledge in the CRS model, bilinear pairings, and various assumptions. Compare non-generic and generic model approaches, focusing on the Generic Bilinear Group Model. Investigate soundness in GBGM, the intuition behind constructing arguments, and subarguments including 1-sparsity. Learn about solving systems of polynomial equations in this cryptographic context.
