i-TRACE - IoT Transport Assured for Critical Environments

i-TRACE通过使用基于机器学习和区块链的网络安全方法进行创新，并使用增强的物联网网关。它将解决保护物联网中高度流行的受限设备的挑战，特别是在分布式和分散网络（公用事业、交通、智慧城市等）中。虽然这些设备降低了功耗并支持“即装即弃”部署，但它们缺乏使用典型安全技术（如基于签名的方法）的能力。i-TRACE将实现一种引入设备认证/授权机制的方法。网关路由器将能够定期确定设备的身份并检测被篡改的设备。如果黑客引入了恶意软件/病毒，可能会破坏传感器发送到GW路由器的数据，它将能够检测到设备已被破坏。从设备发送的数据也将通过使用相当轻量级的加密算法来保护。然后，数据将传输到云服务器，并使用区块链进行签名，然后与来源元数据一起存储在安全数据湖中。最终用户将能够在需要时通过与区块链交叉检查消息来读取和检测数据的真实性，以获得地面真相。由于区块链是不可变和防篡改的，因此它在原则上是安全的，不能被更改。这些数据还将由机器学习系统进行分析，以运行最先进的威胁分析算法。这将识别和优先处理异常/异常值，供安全分析师采取行动。i-TRACE将在一个具有高度社会影响力的领域展示其方法：水行业。伦敦是世界上最面临淡水枯竭风险的十大城市之一。我们目前的使用量是每人每天150升；为了可持续发展，我们需要将其减少到118升。节约的三分之一需要通过提高用水效率来实现，即减少用水量，同时降低家庭用水成本。i-TRACE将展示其实现安全、低成本、长寿命智能水表的方法。这反过来将使家庭行为的方法得以改变。i-TRACE伙伴关系包括相关的跨部门专业知识，以实现成功的创新交付。合作伙伴包括：思科国际有限公司、诺森布莱恩水务有限公司、英国电信有限公司、Senseon科技有限公司、华威大学（华威制造集团）。

i-TRACE innovates through the use of an ML and blockchain-based cybersecurity approach using enhanced gateways for IoT. It will tackle the challenge of securing constrained devices highly prevalent in IoT particularly in distributed and dispersed networks (utilities, transport, smart city etc). While reducing power use and enabling 'fit and forget' deployment these devices then lack the capacity to use typical security techniques such as signature-based approaches.i-TRACE will implement an approach that introduces a device authentication/authorization mechanism. The gateway router will be able to regularly determine the identity of the devices and detect tampered devices. If a hacker introduces a malware/virus which might potentially corrupt the data which the sensor is sending to the GW router, it would be able to detect the device has been compromised. The data sent from the device will also be secured by using fairly lightweight encryption algorithm. The data will then make its way to the cloud server and be signed with a blockchain and stored in the secure data lake along with the provenance metadata. The end user will be able to read and detect the authenticity of the data whenever it needs by crosschecking the messages with the blockchain to obtain the ground truth. Since blockchain is immutable and tamper-proof, it is secure in principle and cannot be altered. This data will also be analysed by a ML system to run state-of-the-art threat analysis algorithms. This will identify & prioritise anomalies/outliers for action by security analysts.i-TRACE will demonstrate its approach in a high social impact sector: the water industry. London is in the top 10 cities in the world most at risk of running out of freshwater. Our current use is 150 litres per person per day; to be sustainable, we need to reduce this to 118 litres. A third of this saving needs to come from more efficient use -- reducing consumption -- but while reducing the cost of water for households. i-TRACE will demonstrate its approach to enable a secure yet low-cost, long-life approach to smart water meters. This in turn will enable approaches to household behaviour change.The i-TRACE Partnership includes relevant cross sector expertise to enable successful innovation delivery. Partners include: Cisco International Limited | Northumbrian Water Limited | BT plc | Senseon Tech Ltd | University of Warwick (Warwick Manufacturing Group).
