| 讲座内容 | We simply revisit the notions, security models, and constructions about aggregate signature schemes. We show a weakness about the security model by demonstrate a practical attack that it cannot withstand. Then we suggest a very simple but strong security model, and modify an existing scheme to derive a provably secure aggregate schemes under the designated verifier variant of the new security model. We also discuss some potential application areas of aggregate signature schemes. |
