Abstract

The rise of 5G mobile broadband networks creates new possibilities for the Internet of Things. Billions of devices will provide comprehensive services, including e-health applications, smart grids, and industry 4.0. Distributed ledger technologies solve most security and privacy threats of current IoT systems connected to a cloud or multi-access edge communication (MEC). Unfortunately, the volume of transactions imposed by 5G networks prevents blockchain-based solutions due to scalability issues. Nonetheless, emerging solutions based on directed acyclic graphs (DAG), still require some form of centralization or global view. This article proposes DAGSec, a hybrid distributed ledger architecture that provides a secure Internet of Things environment with high throughput and low latency. Our proposal uses directed acyclic graphs and local transaction validation instead of global transaction validation to attain a high transaction rate. Furthermore, we propose a blockchain-based witness system to approximate chronological order of independent transactions.
DAGSec:用于物联网安全管理的混合分布式账本架构
5G移动宽带网络的兴起,为物联网创造了新的可能性。数十亿设备将提供全面的服务,包括电子医疗应用、智能电网和工业4.0。分布式账本技术解决了当前连接到云或多访问边缘通信(MEC)的物联网系统的大多数安全和隐私威胁。不幸的是,由于可扩展性问题,5G网络带来的交易量阻碍了基于区块链的解决方案。尽管如此,基于有向无环图(DAG)的新兴解决方案仍然需要某种形式的集中化或全局视图。本文提出了DAGSec,这是一种混合分布式账本架构,可提供具有高吞吐量和低延迟的安全物联网环境。我们的建议使用有向无环图和本地交易验证来代替全局交易验证来获得高交易率。此外,我们提出了一个基于区块链的见证系统,以近似独立交易的时间顺序。
