5G has revolutionized the entire world from academia to industries. 5G is a new type of mobile communication network with the characteristics of high speed, low delay, and large connection. It is the network infrastructure to realize man-machine interconnection. In order to meet the requirements of diverse 5G application scenarios, the key performance indicators of 5G are more diversified. It provides users with augmented reality, virtual reality, high-definition video, and other more immersive acme business experiences, more to solve the people and things, and communication problems, mobile medical, networking, intelligent household, industrial control, environmental monitoring, and Internet of Things application requirements.

Ultimately, 5G will penetrate all industries and sectors of the economy and society, and become a key new infrastructure to support the digitalization, networking, and intelligent transformation of the economy and society. Some of the security issues that are possible in 5G and beyond networks include eavesdropping, unauthorized access, and demolishing integrity. Traditional techniques such as cryptography can be used to provide security services.

The Special Issue aims to present state-of-the-art research in utilizing 5G networks for security and privacy technologies on multimedia applications and to offer a forum for experts to publish their recent advances and views on future perspectives in 5G communication networks.
