工业互联网联盟发布有关区块链、IIoT的数据所有权的论文

2020-7-29 12:52

 

昨天,工业互联网联盟(IIC)发布了一份关于数据控制的白皮书,其中区块链是工业物联网(IIoT)解决方案的一部分。IIC最近与可信物联网联盟合并。


在本文中,简要介绍了使用区块链的好处,其中最大的好处之一是能够可靠地记录IoT数据,确保数据在事后不会被篡改。具体的IIoT用例包括设备监视(如记录服务级别(SLA)违规)、边界自治(包括记录故障而不需要现场检查),以及诸如卡车里程表欺诈预防等。


卡车运输是本文探讨的用例。更具体地说,是司机是否开得太快以及其他服务水平违规。


IIC德国区域团队负责人Daniel Burkhardt说:“在基于区块链的IIoT解决方案中,解决方案架构师有几种管理功能分布和数据所有权的选择。”“他们必须考虑系统的性能和可靠性,以及网络可靠性、带宽和延迟,以及解决方案的使用属性。”


在这个例子中,列出了三种数据所有权的可能路径。数据由私钥控制,而私钥存在于钱包中。因此,一种方法是让平台管理器集中控制钱包。这使得实现和管理钱包变得更加容易。但使用数据的客户必须相信数据没有被平台运营商篡改,因此这里的信任度较低。


第二种方法是将钱包放在设备上(资产控制),前提是钱包可以存储在可防篡改的可信硬件上。其优点是增加了现场的安全性,它将传感器直接连接到区块链上。缺点是可信硬件的成本,以及对硬件是否防篡改所需要的信心。此外,它的维护成本更高。


第三种方法是使用智能契约来实现业务逻辑,它可以包含权限模型并在各方之间执行业务逻辑。此方法可以与前两种方法结合使用。


与此同时,IIC之前为区块链和物联网项目举办了智能建筑挑战赛。选举结果于今年2月公布。


我们之前已经探索了几个其他的IIoT应用程序。例如,Xage是参与合并IIoT和区块链的初创公司之一。该公司获得了通用电气风险投资公司(GE Ventures)的支持,并与美国空军(U.S. Air Force)签订了网络安全合同。沃达丰与Energy Web合作,将电网资产与区块链和物联网连接起来。

 

Yesterday the Industrial Internet Consortium (IIC) released a whitepaper about the control of data where blockchain is part of an industrial IoT (IIoT) solution. The IIC recently merged with the Trusted IoT Alliance.

In the paper, the benefits of using blockchain are briefly addressed with one of the biggest being the ability to log IoT data with confidence that the data is not tampered with after the fact. Specific IIoT use cases include device monitoring such as logging service level (SLA) violations, edge autonomy including logging of faults without the need for an onsite inspection, and things like truck odometer fraud prevention.

Trucking was the use case explored in the paper. More specifically, whether the driver was going too fast and other service level infractions.

“Solution architects have several options for managing the functional distribution and data ownership in blockchain-based IIoT solutions,” said Daniel Burkhardt, IIC German Regional Team Lead. “They must consider the system’s performance and trustworthiness aspects as well as network reliability, bandwidth and latency, as well as solution usage attributes.”

In the example, three potential routes to data ownership are outlined. The data is controlled by private keys, which in turn live in wallets. So one approach is to have the platform manager centrally control the wallets. This makes it easier to implement and manage wallets. But the customer using the data has to trust the data wasn’t tampered with by the platform operator, so trust is weaker here.

A second approach is to have the wallets live on the device (asset-controlled) provided there’s tamperproof trusted hardware where the wallet can be stored. The advantage is the added security in the field, which links the sensor directly to the blockchain. The downsides are the cost of the trusted hardware, and the confidence needed in whether the hardware is tamperproof. Plus it’s more expensive to maintain.

The third approach is to use smart contracts to implement business logic, which can incorporate permission models and execute business logic between the parties. This approach can be combined with either of the first two.

Meanwhile, the IIC previously ran a Smart Buildings Challenge for blockchain and IoT projects. The results were announced in February.

We’ve previously explored a few other IIoT applications. For example, Xage is one of the startups that has been involved in combining IIoT with blockchain. It received backing from GE Ventures and a cybersecurity contract with the U.S. Air Force. And Vodafone has teamed up with Energy Web to link power grid assets with blockchain and IoT.
