摘要

在本文中，我们展示了Lin和Wu提出的具有欺诈者识别的不可否认(t, n)阈值签名方案的弱点。在我们的攻击方法中，签名组中的作弊者可以在不被识别的情况下破坏签名的正确性。

Cryptanalysis on Lin and Wu’s Undeniable (t, n)-Threshold Signature Scheme with Cheater Identification

In this manuscript, we show the weakness of the undenialbe (t, n)-threshold signature scheme with cheater identification proposed by Lin and Wu. In our attack method, if cheater in the signer group is able to violate the correctness of the signature without being identified.
