在STOC2003上,提出了一个公共参考串模型(CRS)下的非交互的可重用的统计绑定的非延展承诺方案。该方案的CRS由4部分构成:承诺的公钥、签名方案的公钥、广义单向哈希函数和一个对串0的承诺。我们使用2个签名方案构造了一个此类方案,方案中CRS只有2部分:模糊承诺的公开参数和签名方案的公钥。因此,新方案的CRS更短些。
On STOC2003, a non-interactive, reusable statistical binding non-stretch commitment scheme is proposed in the Common Reference String Model (CRS). The CRS consists of four parts: committed public key, public key of signature scheme, generalized unidirectional hash function and a commitment to string 0. We constructed a solution of this type using two signature schemes with only two parts of the CRS: the public parameters of the fuzzy promises and the public key of the signature scheme. Therefore, the new program has a shorter CRS.
