针对基于图的大数据系统，设计了一种通用指定验证者传递签名（）方案。具体地说，它允许传递签名保持器用传递签名说服指定的验证者。然而，现有的方案不能直接应用于多验证者的情况下。因此，在本文中，我们将这一概念扩展到通用指定多验证者传递签名（）方案。也就是说，我们的新方案允许一个传递签名保持器指定的签名多验证者。此外，对于所提出的方案，我们形式化的安全概念，并证明其安全性的随机预言模型。我们还分析了我们的计划的性能，以证明其效率。
A Universal Designated Verifier Transitive Signature () scheme is designed for the graph-based big data system. Specifically, it allows a transitive signature holder to convince the designated verifier with a transitive signature. Nevertheless, existingschemes cannot be directly employed in the scenarios when multi-verifier are involved. Thus, in this paper, we extend the notion to the Universal Designated Multi-Verifier Transitive Signature () scheme. Namely, our new scheme allows a transitive signature holder to designate the signature to multi-verifier. Furthermore, for the proposed scheme, we formalize its security notions and prove its security in the random oracle model. We also analyse the performance of our scheme to demonstrate its efficiency.
