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，一个缺口正在出现，这揭示了许多不同的网络物理系统领域对性能和安全的挑战。特别是，数字领域的网络安全保护提供了令人满意的保护和核查机制，这种机制目前在物理域没有类似的机制，从而限制了网络物理系统的核查能力。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，在那里它们应该被允许协调，而不考虑之前的任何物理或数字关系。与其依赖高风险的人工参与或专门的硬件，使用共同背景的可测量和可验证的细节来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。提出了“上下文指纹”的概念，作为一种在不需要计算密集型密码学的情况下弥合这一空白的方法。它是一种允许两个不同的设备观察事件、处理测量数据以及创建和交换上下文指纹以验证共享属性的技术。这个项目探索了DEVISE的上下文指纹识别的CPS基础。这一概念将经过经验评估，展示如何促进物联网设备之间可用和安全的信任引导。

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.
