(t, n) Threshold Digital Signature Scheme with Traceable Signers against Conspiracy Attacks
Lin-Sen Zhao, Jing-Mei Liu · 2013
In this paper, one group-oriented (t, n) threshold digital signature schemes with traceable signers are proposed by introducing the white key technology. We also discuss the security and the characteristic of the schemes and show that the new schemes can withstand conspiracy attacks without attaching a secret number and can avoid the forgery attacks. In addition, we show that any outsider can trace back to find who the signers are.
