BIoTS-Path: Certification Transmission of Supply Chains Based on Blockchain–Internet of Things Architectures by Validating the Information Path

Abstract

A food traceability system (FTS) can record information about processes along a production chain to determine their safety and quality. Under the Internet of Things (IoT) concept, the communication technologies that support FTSs act as platforms for mass access to information with limited security. However, the integrity of the collected data is not immune to security attacks. This paper proposes a point-to-point information transmission path with no edges or access boundaries (no intermediaries) to transmit data with integrity. This route is possible thanks to the architectural articulation of a hardware device (sensor BIoTS) at the perception layer, with the Blockchain architecture at the application layer. This pairing makes an ecosystem with the ability to trace and certify in parallel the products, the supply chain processes, and the data recorded in it possible. The design of the security testing ecosystem is based on the theoretical and technical principles of cybersecurity. It is executed through mathematical models that define the probability of attacks’ success against the transmitted data’s integrity. The security tests performed allow for establishing that this BIoTS information transmission route is unlikely to suffer from transmission vulnerabilities and that it is not prone to security attacks against integrity. This work paves the way toward fully integrating Blockchain technology in dedicated IoT architectures.

An Analysis of Blockchain-Based IoT Sensor Network Distributed Denial of Service Attacks

“…Researchers have identified blockchain as a possible solution to secure IoT devices and networks. This has led to the development of the "Blockchain of Things" by integrating blockchain and IoT technologies [16].…”

“…The reliability of IoT data refers to the quality and trustworthiness of the information [14]. Blockchain technology is used to ensure the security and integrity of this data by employing encryption algorithms, digital signatures, and timestamps [16]. By enhancing the reliability of blockchain data, the performance of data transmission over blockchain networks is improved [14,15].…”
