Abstract

The expansion of IoT devices over the past years has led to the development of smart ecosystems susceptible to cyberattacks. These ecosystems include smart industries and smart home security systems. However, when these devices are widely deployed and generate significant amounts of data, this data must be securely stored on the cloud to prevent it from being compromised by serious cyber attacks. Although traditional security methods partly meet the need to protect the privacy and security of smart IoT ecosystems, their centralized structure and limited computing power make them inefficient. However, recent advancements in blockchain technology have made it possible to employ decentralized architectures to enhance the cybersecurity defense mechanisms of IoT ecosystems. The utilization of blockchain-enabled methodologies is considered one of the most auspicious advancements in the domain of the IoT. These techniques offer a secure and decentralized mode of communication among internet-connected devices. This study presents a blockchain-based novel framework to enhance the cybersecurity measures of smart IoT ecosystem installations. The proposed framework prioritizes the immutability of devices and users present in such environments and incorporates smart contracts to ensure their overall security. Furthermore, the system includes a module for regularly verifying the firmware of connected devices by comparing them to the valid firmware hashes present in the smart contract's storage. The proposed approach has also come up with the idea of blacklisting the malicious IP addresses trying to connect with IoT ecosystems network.

利用区块链增强物联网生态系统的网络安全防御
过去几年,物联网设备的扩张导致了易受网络攻击的智能生态系统的发展。这些生态系统包括智能工业和智能家庭安全系统。然而,当这些设备被广泛部署并产生大量数据时,这些数据必须安全地存储在云中,以防止受到严重的网络攻击。虽然传统的安全方法在一定程度上满足了保护智能物联网生态系统隐私和安全的需求,但其集中的结构和有限的计算能力使其效率低下。然而,最近区块链技术的进步使得采用分散式架构来增强物联网生态系统的网络安全防御机制成为可能。使用支持区块链的方法被认为是物联网领域最吉祥的进步之一。这些技术在连接互联网的设备之间提供了一种安全和分散的通信模式。 本研究提出了一个基于区块链的新框架,以增强智能物联网生态系统安装的网络安全措施。拟议的框架优先考虑在这种环境中存在的设备和用户的不变性,并结合智能合约以确保其整体安全性。此外,该系统还包括一个模块,用于通过将连接设备的固件与智能合约存储中存在的有效固件哈希值进行比较来定期验证连接设备的固件。该方法还提出了将试图连接物联网生态系统网络的恶意IP地址列入黑名单的想法。
