Guest editorial: Recent advances in mobile communication network security

The landscape of mobile communication networks has been evolving so rapidly. Over the last decades, 3G/4G achieved unprecedented success thanks to its advancement in IP for all, and high-speed, mobile and ubiquitous Internet access. Compared with 3G/4G, 5G now makes significant advances in terms of connectivity, data rate and latency, which shifts from the conventional people-to-people to the modern people-to-things and things-to-things communication paradigm. As the next standardization focus, 6G will further build a ubiquitous network that realizes the integrated communication of air, space, earth and sea, boost the data rate 100 X faster than that of 5G, enable machine intelligence through AI, and many others. Expectedly, 6G will have much broader application prospects such as virtual or augmented reality, Internet of Things, Industrial Internet, unmanned driving, and smart factories.
