Neetu Rani, Narinder Yadav, Ishdeep Singla, Sujoy Ray · 2025
The development of key technologies including Transport Layer Security (TLS) and Datagram TLS (DTLS) , Message Queuing Telemetry Transport , Advanced Encryption Standard, Security Information and Event Management , National Institute of Standards and Technology and the other sixth-generation (6G) networks, which are characterized by ultra-high speed, low latency, and artificial intelligence (AI)-based automation, is a consequence of advancements in global communications technology. The 6G networks, along with the Internet of Things (IoT) networks, have expanded the capabilities of the interconnected world, accommodating billions of devices in healthcare, smart cities, and industrial automation. However, the increasing reliance on these interconnected webs of networks poses tremendous risks in terms of security and privacy. The proposed research highlights the growing demand for 6G and IoT networks for secure communications and the protection against cyberattacks, privacy violations, quantum computing risks, and other emerging threats. The proposed research also highlights primary concerns like the massive scale of the connectivity, low-power consuming IoT devices, AI-powered cyberattacks, and regulatory fragmentation. In addition, the proposed research presents advanced security solutions based on post-quantum cryptography (PQC), trust models with blockchain, AI-based intrusion detection, and privacy-preserving mechanisms such as differential privacy, homomorphic encryption, and others. Further, the research discusses the role of international legislative policies in defining and developing secure communication protocols for the next generation.
