Speaker: Aggelos Kiayias Day: Wednesday, 1/24/2007 Room: ITEB 336 Time: 2:00-3:30pm Title: Zero-Knowledge Proofs of Knowledge Abstract. Since their introduction in the 80's zero-knowledge proofs of knowledge have been proven to be one of the most indispensable tools in cryptographic protocol design. In this talk we will review some classic results in the design of such protocols as well as present some of their major applications. Reading : O.
