Title: Privacy-Preserving Techniques to Blockchain: The Ring Signature Approach

时间:419日下午15:00

地点:东五楼210

Abstract:

Abstract: Ring signature is a kind of anonymous signature. Verifier only knows that the signer is a user within a group, yet does not know the identity of this signer. In this talk, we will cover the basics of ring signature and linkable ring signature, including the concept, applications, technical constructions and variants. We will further relate linkable ring signature to cryptocurrencies and discuss how it can provide privacy to users in Blockchain. We will also discuss some interesting future works in this area.
