本文对具有多签名无密钥聚合和从聚合签名中识别无效消息功能的分组测试聚合签名进行了全面研究，以减少大量消息的签名总量。我们的贡献是：(i)通过考虑相关工作，如容错聚合签名和具有检测功能的非交互式聚合mac（即对称情况），形式化强安全概念，包括组测试聚合签名的可靠性；（ii）从集合签名中泛化、综合地构建群测集合签名；(3)给出了一个聚合签名方案，该方案可应用于我们的群测试聚合签名的一般构造，具有形式化的安全性。
In this paper, we comprehensively study group testing aggregate signatures that have functionality of both keyless aggregation of multiple signatures and identifying an invalid message from the aggregate signature, in order to reduce a total amount of signature-size for lots of messages. Our contribution is (i) to formalize strong security notions including soundness for group testing aggregate signatures by taking into account related work such as fault-tolerant aggregate signatures and non-interactive aggregate MACs with detecting functionality (i.e., symmetric case); (ii) to construct group testing aggregate signatures from aggregate signatures in a generic and comprehensive way; and (iii) to present an aggregate signature scheme which we can apply to our generic construction of group testing aggregate signatures with the formalized security.
