部分盲签名通过在最终的签名数据中包含签名者和用户协商一致的公用信息(签名发布日期,电子货币的金额)来扩展了盲签名的概念。该文在随机预言机模型下提出了一个高效的可证安全的部分盲签名方案,该方案利用一个公开可行的算法提前计算出将要在随后的部分盲签名协议中用到的公钥和私钥,因此该方案Okamoto-Schnorr盲签名方案具有相同的安全性,并且不会造成额外的系统开销。
Partial Blind Signatures extend the concept of blind signatures by including in the final signature data public information (date of signatures issuance, amount of electronic money) that the signer and the user agree on. In this paper, an efficient and partially verifiable secure blind signature scheme is proposed under the random oracle model. The scheme uses a publicly available algorithm to calculate in advance the public and private keys to be used in the subsequent partially blind signature protocol , So the scheme Okamoto-Schnorr blind signature scheme has the same security, and does not cause additional system overhead.
