Random Oracle Model

Composable Non-interactive Zero-knowledge Proofs in the Random Oracle Model

In this talk, I will give an overview of techniques to compile Sigma protocols—a popular class of interactive cryptographic proofs—to non-interactive proofs that guarantee security when used in any larger protocol context. The aim of the talk will be to provide an introduction to the area to system designers who typically use cryptographic tools as a black box, while also providing insight into some interesting technical subtleties that I uncovered in a recent work.
