Abstract
The traditional cloud-based Internet of Things (IoT) architecture places extremely high demands on computers and storage on cloud servers. At the same time, the strong dependence on centralized servers causes major trust problems. Blockchain provides immutability, transparency, and data encryption based on safety to solve these problems of the IoT. In this paper, we present a distributed secure edge computing architecture using multiple data storages and blockchain agents for the real-time context data integrity in the IoT environment. The proposed distributed secure edge computing architecture provides reliable access and an unlimited repository for scalable and secure transactions. The architecture eliminates traditional centralized servers using an edge computing framework that represents cloud computing for computer and security issues. Also, blockchain-based edge computing-compatible IoT design is supported to achieve the level of security and scalability required for data integrity. Furthermore, we present the blockchain agent to provide internetworking between blockchain networks and edge computing. For experimenting with the proposed architecture in the IoT environment, we implement and perform a concrete IoT environment based on the EdgeX framework and Hyperledger Fabric. The evaluation results are collected by measuring the performance of the edge computing and blockchain platform based on service execution time to verify the proposed architecture in the IoT environment.
Highlights
The Internet of Things (IoT) is an ever-present network of intelligent and network-available objects and people
The data is stored in the data repository and the blockchain agent sends the data to the blockchain network for enabling data integrity in the IoT environment
We proposed a distributed secure edge computing architecture using multiple data repositories that combines blockchain platforms and edge computing frameworks to ensure the safety and integrity of IoT data through the real-time data integrity
Summary
The IoT is an ever-present network of intelligent and network-available objects (called “things”) and people. By integrating the blockchain network into the edge computing environment, the system could present reliable control and access over the network, repository, and computing via distributed edge devices. We propose a distributed secure edge computing architecture using multiple data repositories that combine blockchain platforms and edge computing frameworks for ensuring the safety and integrity of IoT data. Based on the blockchain, edge computing achieves the level of security and scalability required for data integration in IoT environments. EdgeX-based edge computing to provide secure data integrity in the IoT environment.
