Implementation of VPN (Virtual Private Network) for Communication Security Between IoT Devices on Smart Home Networks
Keywords:
Internet of Things, Smart Home, Virtual Private Network, WireGuard, Network SecurityAbstract
The development of Internet of Things (IoT) technology has led to the creation of Smart Home systems that are capable of connecting various smart devices through the internet network. However, this increase in connectivity poses a high security risk due to the potential for interception and cyber attacks on communication data between devices. Therefore, an efficient security solution is needed to maintain data confidentiality and integrity. This study aims to analyze the effectiveness of implementing a Virtual Private Network (VPN) as a security mechanism for communication between IoT devices on a Smart Home network, as well as to assess its impact on network performance. The research uses a quantitative experimental approach by conducting tests on two conditions, namely a network without VPN and with VPN using the OpenVPN and WireGuard protocols. The parameters measured include latency, throughput, packet loss, and data security levels through sniffing analysis and intrusion detection. The results show that the implementation of VPN significantly improves communication security by encrypting all data, reducing the number of open ports, and preventing illegal access. Although there was an increase in latency of 27–45% and a decrease in throughput of around 7–12%, network performance remained stable.
The WireGuard protocol has been proven to be more efficient than OpenVPN in terms of resource usage and connection stability. VPNs are effectively implemented as the primary security layer in Smart Home systems, providing strong data protection without significantly compromising network performance. Further research is recommended to integrate VPNs with Edge Computing and Software Defined Networking to improve system efficiency and scalability.
