II-EN: IoT Event Emulation Environment (IoTE^3) based on Cyber-Physical Integration

新兴的物联网（IoT）具有巨大的潜力，使人们能够与医疗保健、智能城市、制造业、交通运输等应用中前所未有的众多物理设备和系统进行通信，并对其进行远程控制、监控和管理。 研究人员需要一个物联网研究基础设施，使他们能够解决与物联网相关的挑战。IoTE^3（物联网事件仿真环境）是为此目的提出的一种新的研究基础设施。它将利用爱荷华州州立大学（ISU）现有的研究平台来支持各种物联网研究，从物联网信息学到基于物联网的智能物理系统，再到物联网安全攻击和预防。它将在完成后免费提供给公众，以便实验者可以进行物联网网络和网络安全的实践活动。此外，IoTE^3将与ISU的网络防御竞赛（CDC）平台集成，使学生和教师面临物联网特有的安全挑战。IoTE^3将建立在现有的ISEAGE（Internet Scale Event and Attack Generation Environment，互联网规模事件和攻击生成环境）基础上，该环境创建了一个虚拟互联网，用于研究、设计和测试网络防御机制。在受控的ISEAGE环境中，真实世界的事件和攻击可以针对不同的环境配置进行测试，这与基于计算机的模拟不同。目前，ISEAGE仅限于模拟传统互联网上的事件和攻击。IoTE^3旨在增强和扩展用于物联网研究的ISEAGE。IoTE^3提供了一个基于物理和网络环境集成的独特仿真环境，具有可扩展性，灵活性和真实性。物理环境将由实际物联网设备的物理网络组成。这些物理物联网网络中的每一个都可以自己托管小规模的本地化实验。它们还可以连接到ISEAGE以进行更大规模的实验。网络环境将由多个高端服务器（物联网仿真器）组成，以托管可配置数量的虚拟物联网网络。每个虚拟网络都可以配置为基于跟踪的仿真，以重放从物理环境捕获的IoT流量，或者基于模型的仿真，以基于从捕获的IoT流量中学习的模型生成合成流量。网络和物理环境将通过ISEAGE相互连接和互动。

The emerging Internet of Things (IoT) has tremendous potential to allow people to communicate with and remotely control, monitor, and manage an unprecedented multitude of physical devices and systems for applications like healthcare, smart cities, manufacturing, transportation, etc. IoT devices will generate large amounts of information-rich data, and the associated security risks are far beyond what people have previously seen and experienced. Researchers need an IoT research infrastructure that allows them to address the challenges associated with the IoT. IoTE^3 (IoT Event Emulation Environment) is a new research infrastructure proposed for this purpose. It will leverage an existing research platform at Iowa State University (ISU) to support a variety of IoT research, ranging from IoT Informatics to IoT-based Intelligent Physical Systems to IoT Security Attacks and Prevention. It will be freely available to the general public upon completion, so that experimenters can undertake hands-on activities with IoT networking and cyber security. In addition, IoTE^3 will be integrated with ISU's Cyber Defense Competition (CDC) platform, exposing students and faculty to the security challenges specific to the IoT. IoTE^3 will be built upon the existing ISEAGE (Internet Scale Event and Attack Generation Environment), which creates a virtual Internet for the purpose of researching, designing, and testing cyber defense mechanisms. In the controlled ISEAGE environment, real-world events and attacks can be tested against different configurations of the environment, unlike computer-based simulations. Currently, ISEAGE is limited to emulation of events and attacks on the traditional Internet. IoTE^3 is proposed to enhance and expand ISEAGE for IoT research. IoTE^3 provides a unique emulation environment based on the integration of physical and cyber environment that is scalable, flexible and realistic. The physical environment will consist of physical networks of actual IoT devices. Each of these physical IoT networks can host small-scale localized experiments by itself. They also can be connected to the ISEAGE to host larger-scale experiments. The cyber environment will consist of multiple high-end servers (IoT emulators) to host a configurable number of virtual IoT networks. Each virtual network can be configured as either a trace-based emulation to replay IoT traffic captured from the physical environment, or a model-based emulation to generate synthetic traffic based on models learned from the captured IoT traffic. The cyber and physical environments will be connected and interact with each other through ISEAGE.
