数字签名是确保命名数据网络（NDN）系统所交付内容的完整性和真实性的基本构建块。然而，NDN开源库采用的当前数字签名方案具有较高的计算和通信开销，使得它们不适合高吞吐量应用，如视频流和虚拟现实游戏。在这篇海报中，我们提出了一个实时数字签名机制的NDN的基础上离线在线签名框架称为无结构和紧凑的实时认证方案（SCRA）。我们的签名机制显著降低了签名和验证成本，并提供了不同的变体来优化应用程序的特定要求（即签名开销，验证开销或通信成本）。我们的实验结果表明，SCRA是一个合适的框架延迟敏感的NDN应用程序。
Digital signatures are a fundamental building block for ensuring integrity and authenticity of contents delivered by the Named Data Networking (NDN) systems. However, current digital signature schemes adopted by NDN open source libraries have a high computational and communication overhead making them unsuitable for high throughput applications like video streaming and virtual reality gaming. In this poster, we propose a real-time digital signature mechanism for NDN based on the offline-online signature framework known as Structure-free and Compact Real-time Authentication scheme (SCRA). Our signature mechanism significantly reduces the signing and verification costs and provides different variants to optimize for the specific requirements of applications (i.e. signing overhead, verification overhead or communication cost). Our experiments results show that SCRA is a suitable framework for latency-sensitive NDN applications.
