| 摘 要： | 为抵抗量子计算的攻击，基于辫群上求根问题的难解性提出了一个同时签名方案。在方案中，签名发起者和响应者分别选择各自的关键参数，保证了双方的公平性。分析表明在两个关键参数公布前，发起者和响应者产生的签名均是模糊的；关键参数公布后，两个签名被同时绑定。 |
| 关 键 词： | 辫群 求根问题 同时签名 |

| Abstract: | To resist the quantum computing, this paper proposed a concurrent signature scheme over braid group on the difficulty of root extraction problem. The initial signer and the matching signer chose two keystones, respectively, which guaranteed the fairness. Analysis shows that before releasing the keystones, both signatures are ambiguous while upon release of the keystones, both signatures become binding to their true signers concurrently. |
| Keywords: | braid group root extraction problem concurrent signature |
