Digital multi-signature scheme based on bilinear pairing

Blog Article

Based on bilinear pairing and three complicated problems,a new digital multi-signature scheme was pro-posed.In the new scheme,the advantage of fast signature in broadcasting digital multi-signature was applied to se-quential digital multi-signature.By changing the general mechanism of signature,signing could be done simultane-ously by the signers.Then,the signature ORG SUNFLOWER SEEDS was sent to verifier after it was verified by trusted third party.The trans-formation from concurrent signature to sequential signature was finally realized by the verifier.

The security capa-bilities in three complicated problems,anti-fake attack and anti-conspiracy attack from some members of the new scheme were analyzed.Proposed scheme has many advantages over the old ones,such as fewer Camera bags and cases calculation,simpler algorithm,faster signing,higher security.
