车辆网络、智能电网和其他智能基础设施等时间关键型网络的安全高效运行在当今社会中至关重要。最大限度地减少安全机制对此类网络的影响至关重要，以便时间关键系统的安全可靠运行不会受到干扰。例如，如果加密操作引入的延迟对碰撞前制动汽车的可用时间产生负面影响，则汽车可能无法及时安全停车。特别是，现有的数字签名作为主要的认证机制，引入了巨大的计算和通信开销，因此无法完全满足此类时间关键网络的实时处理要求。在本文中，我们介绍了一套新的实时数字签名，称为无结构和紧凑实时身份验证（${SCRA}$），由硬件加速支持，以在时间关键的网络中提供延迟感知身份验证。 ${SCRA}$ 是一种新颖的签名框架，可以将任何安全聚合签名转换为签名者高效签名。我们使用压缩 RSA、BGLS 和 NTRU 签名实例化 ${SCRA}$ 框架。我们的分析和实验评估验证了 ${SCRA}$ 方案相对于其基本签名和最先进的方案具有显着的性能优势。此外，我们通过在车载片上系统以及服务器级通用图形处理单元上的高度优化实现，将 ${SCRA}$ 方案的性能推向边缘。我们证明 ${SCRA}$ 是安全的（在随机预言模型中），并表明 ${SCRA}$ 可以为时间关键型应用程序中的身份验证提供理想的替代方案。
The secure and efficient operation of time-critical networks, such as vehicular networks, smart-grid, and other smart-infrastructures, is of primary importance in today’s society. It is crucial to minimize the impact of security mechanisms over such networks so that the safe and reliable operations of time-critical systems are not being interfered. For instance, if the delay introduced by the crypto operations negatively affects the time available for braking a car before a collision, the car may not be able to safely stop in time. In particular, as a primary authentication mechanism, existing digital signatures introduce a significant computation and communication overhead, and therefore are unable to fully meet the real-time processing requirements of such time-critical networks. In this paper, we introduce a new suite of real-time digital signatures referred to as Structure-free and Compact Real-time Authentication ( ${SCRA}$ ), supported by hardware acceleration, to provide delay-aware authentication in time-critical networks. ${SCRA}$ is a novel signature framework that can transform any secure aggregate signature into a signer efficient signature. We instantiate ${SCRA}$ framework with condensed-RSA, BGLS, and NTRU signatures. Our analytical and experimental evaluation validates the significant performance advantages of ${SCRA}$ schemes over their base signatures and the state-of-the-art schemes. Moreover, we push the performance of ${SCRA}$ schemes to the edge via highly optimized implementations on vehicular capable system-on-chip as well as server-grade general purpose graphics processing units. We prove that ${SCRA}$ is secure (in random oracle model) and show that ${SCRA}$ can offer an ideal alternative for authentication in time-critical applications.
