Lin在2012年提出了内容抽取签名和通用指定验证者签名相结合的概念。具体地，它允许提取的签名保持器将签名指定给预期的验证者。然而，当涉及多个验证者时，现有的设计变得低效。为了提高效率，本文将其推广到通用指定多验证者内容提取签名（UDMVCES）。实现我们的新方案，提取的签名保持器可以有效地指定签名的多个验证者。此外，我们提供了安全性的概念，并证明了所提出的方案的安全性在随机预言模型。为了说明UDMVCES方案的有效性，我们分析了该方案的性能，分析表明，新方案的计算量和签名长度与验证者的数目无关。
A notion combined the content extraction signature and the universal designated verifier signature was put forth by Lin in 2012. Specifically, it allows an extracted signature holder to designate the signature to a prospective verifier. However, existing designs become inefficient when multi verifiers are involved. To improve the efficiency, in this paper, we extend the notion to the universal designated multi verifiers content extraction signature (UDMVCES). Implementing our new scheme, the extracted signature holder can efficiently designate the signature to multi verifiers. Additionally, we provide the security notions and prove the security of the proposed scheme in the random oracle model. To illustrate the efficiency of our UDMVCES scheme, we analyse the performance of it. The analysis shows that the computation costs and signature lengths of the new scheme are independent of the number of verifiers.
