Abstract
With the rapid development and extensive application of 5G networks, their advantages in high speed, low latency, and massive connectivity have provided critical support for digital transformation in society. However, these advancements also bring about complex and diverse security threats. This study aims to systematically analyze the security challenges faced by 5G networks and propose targeted protective technical solutions. By thoroughly investigating the characteristics of the 5G network architecture and its potential vulnerabilities, combined with real-world application scenarios, this paper employs a methodology that integrates theoretical analysis with experimental validation. It focuses on core network security, edge computing security, and user privacy protection. The results indicate that anomaly detection technology based on artificial intelligence can significantly enhance the efficiency of identifying network attacks, while the application of blockchain technology effectively strengthens the trustworthiness and integrity of data transmission. Additionally, this research designs a lightweight encryption algorithm to meet the security requirements of IoT devices under resource-constrained conditions. Overall, this study not only reveals key security risks in 5G networks but also proposes innovative solutions, laying a theoretical and technical foundation for building a safer and more reliable 5G ecosystem. Furthermore, it provides valuable references for the security planning of future 6G networks.
