CPS: Breakthrough: Multi-Sensory Event Detection for Cross-Platform Coordination and Verification

随着研究人员和开发人员从数字系统转向网络物理系统，一个差距正在出现，这揭示了许多不同网络物理系统领域的性能和安全挑战。特别是，数字领域的网络安全保护提供了理想的保护和验证机制，目前在物理领域没有类似的机制，限制了网络物理系统的验证能力。为了说明这一差距，假设两个设备部署在相同的物理空间中，尽管之前存在任何物理或数字关系，但它们应该被允许进行协调。而不是依赖于有风险的人工参与或专门的硬件，使用公共上下文的可测量和可验证的细节自动化配对过程应该允许他们引导信任关系。我们的项目目标是实现基于上下文测量的验证，这将填补网络物理系统中的一个重要空白。“上下文指纹”的概念作为一种不需要计算密集型加密的方法来弥补这一差距。它是一种允许两个不同的设备观察事件的技术，&#8232；处理测量数据，并创建和交换上下文指纹以验证共享属性。这个项目探索了设计的上下文指纹识别的CPS基础。该概念将进行经验性评估，展示如何促进可用和安全引导物联网设备之间的信任。

As researchers and developers move from digital to cyber-physical systems, a gap is emerging that is revealing challenges to performance and security in many different cyber-physical system domains. In particular, cybersecurity protections in the digital domain provide desirable protection and verification mechanisms that currently have no analog in the physical domain, limiting verification capabilities in cyber-physical systems. To illustrate this gap, suppose two devices are deployed in the same physical space where they should be allowed to coordinate despite any previous physical or digital relationship. Instead of relying on risky human involvement or specialized hardware, automating the pairing process using measurable and verifiable details of common context should allow them to bootstrap a trust relationship. Our project goals to enable this verification based on context measurement will fill an important gap in cyber-physical systems.The concept of "context fingerprinting" is offered as an approach to bridge this gap without the need for computationally intensive cryptography. It is a technique to allow two dissimilar devices to observe events,
process measurement data, and create and exchange contextual fingerprints to verify a shared property. This project explores the CPS foundations for context fingerprinting of devise. The concept will be empirically evaluated, showing how to facilitate usable and
secure bootstrapping of trust among IoT devices.
