随着我们的社会加速向物联网过渡，数十亿的物联网设备现在连接到网络。虽然这些小工具提供了巨大的便利，但它们产生的大量数据已经超出了网络的容量。更糟糕的是，这些物联网设备上的传感器获取的数据还包括必须适当处理的敏感用户数据。目前，答案是为数据中心的数据存储提供集线器服务。但是，当数据存放在集中式数据中心中时，数据所有者就失去了对数据的控制，因为数据中心是依赖于数据所有者对服务提供商的信任的集中式解决方案。此外，边缘计算使边缘设备能够更靠近数据源进行收集、分析和操作，边缘附近的数据隐私挑战也是一个棘手的问题。物联网集线器和边缘的大量用户信息泄露使得系统一直不被信任。因此，在边缘附近构建一个分散的物联网系统，给边缘带来真正的信任是必不可少的，也是重要的。为了消除对集中式数据中心的需求，我们提出了一个名为Reja的独特，安全和分散的物联网框架的原型，该框架建立在许可区块链和入侵容忍消息传递系统ChiosEdge之上，ChiosEdge的关键组件是可靠的广播和BFT共识。我们评估了Reja及其子模块ChiosEdge的延迟和吞吐量。
While our society accelerates its transition to the Internet of Things, billions of IoT devices are now linked to the network. While these gadgets provide enormous convenience, they generate a large amount of data that has already beyond the network’s capacity. To make matters worse, the data acquired by sensors on such IoT devices also include sensitive user data that must be appropriately treated. At the moment, the answer is to provide hub services for data storage in data centers. However, when data is housed in a centralized data center, data owners lose control of the data, since data centers are centralized solutions that rely on data owners’ faith in the service provider. In addition, edge computing enables edge devices to collect, analyze, and act closer to the data source, the challenge of data privacy near the edge is also a tough nut to crack.A large number of user information leakage both for IoT hub and edge made the system untrusted all along. Accordingly, building a decentralized IoT system near the edge and bringing real trust to the edge is indispensable and significant. To eliminate the need for a centralized data hub, we present a prototype of a unique, secure, and decentralized IoT framework called Reja, which is built on a permissioned Blockchain and an intrusion-tolerant messaging system ChiosEdge, and the critical components of ChiosEdge are reliable broadcast and BFT consensus. We evaluated the latency and throughput of Reja and its sub-module ChiosEdge.
