论文摘要
在本说明中，我们指出，BLS签名方案的聚合特性产生有效的内容提取签名（CES）。该结构可用于构建数字凭据，以支持各种设置中的选择性披露。有趣的是，该构建非常有效，非常适合在客户服务器或分布式分类帐中使用各种应用程序构建证书发行计划。最后，我们绘制一个将CES与使用NIZK相结合的协议，该协议可以证明对从凭据提取的索赔的谓词满意度，同时保持数据的秘密。
In this note, we remark that the aggregation property of the BLS signature scheme yields an efficient Content Extraction Signature (CES). This construction can be used to build digital credentials that support selective disclosure in various settings. Interestingly, this construction is efficient and well suited to build credential issuance schemes with various applications in the client-server or in the distributed ledger models. Finally, we sketch a protocol that combines the CES with the use of a NIZK which allows to prove predicate satisfaction on claims extracted from a credential, while keeping the data secret.
