Secure Home-WiFi: A Blockchain-Enhanced Intrusion Prevention System for Securing Home Wireless Networks

Abstract

With the significant increase and growing expansion in the use of smart devices within homes, home wireless networks have become more vulnerable to direct cyber-attacks such as unauthorized access attempts, identity theft, and brute force attacks against Wi-Fi protocols in general. Although standard and traditional security technologies such as WPA2/WPA3 encryption and MAC filtering provide a basic level of protection, they still suffer from security issues in the form of vulnerabilities that can be exploited and local log manipulation. To overcome these challenges, this research proposes a blockchain-based system to prevent intrusions into home wireless networks. The system relies primarily on real-time monitoring of traffic through the router to detect suspicious access attempts, using a special distributed ledger (blockchain) to store lists of trusted devices and security logs in a tamper-proof and forgery-proof manner. This system prevents unauthorized devices from joining the network and builds reliable audit logs of security events. This work highlights the potential for integrating blockchain technology with simple, low-cost security solutions to enhance the security of wireless networks in everyday environments.
