Blockchain-Based Secure 5G/6G Communication for Internet of Things Devices in Consumer Electronic Systems

In recent years, blockchain technology has gained prominence beyond cryptocurrencies, finding applications in smart grids and the Internet of Things (IoT). With advancements in AI and next-generation networks, IoT device applications have expanded, requiring high computational resources and reliable data transmission. This study explores the use of 5G/6G communication networks and network slicing to enhance IoT-enabled environments. We propose a model integrating blockchain-based context-aware user authentication, handover, and secure network slicing to manage load and secure data forwarding in 6G networks. Performance evaluations show that our model outperforms existing blockchain-based techniques. The proposed model improves latency by approximately 17.33% compared to the existing model.
