| 摘 要： | 提出一个基于身份的动态门限盲签名方案，签名者不知道他所签的消息的内容，签名信息不可追踪。 方案能够防止私钥生成器（PKG）伪造签名。 同时具有动态安全的特性，将签名的整个周期分成若干个时间段，每个时间段都要更新份额，且利用更新后的份额重构的密钥保持不变。 最后证明了方案的正确性、不可伪造性和鲁棒性。 |

| Abstract: | An ID-based proactive threshold blind signature scheme is presented. The signer does not know the content signed by himself, and the signed message cannot be tracked. In this scheme, the dishonest private key generator cannot impersonate any user at any time. At the same time the scheme has the property of proactive security, that is, the whole lifetime of the signature is divided into several time periods, and the shares of private key need to be renewed in each time period. However, new shares can construct the same private key as old shares, In the end, it is proved that the scheme is correct, non-forgeable and robust. |
