Títol: On Zero-Knowledge Proofs
Resum: Informally speaking, zero-knowledge protocols are cryptographic tools that allow you to prove that you know a secret without revealing it. More precisely, a zero-knowledge proof allows one party to convince another that a statement is true without revealing anything other than the veracity of the statement. This type of proofs were introduced in 1989 as theoretical cryptographic objects, but the appealing properties of the protocols have made them become crucial tools in many real-world applications with strong privacy issues. In this presentation I will explain the main ideas behind zero-knowledge, I will talk about the type of statements that we know can be proved with zero knowledge, and present some of the most outstanding applications of this technology.
