Abstract
"The history of mobile telecommunications is not very old. It has been a bit more than 40 years since the first generation of cellular communications (1G) was launched on the market, offering the possibility of making and receiving phone calls while on the go, even accompanied by a number of technological limitations, including network and system security. Each new generation of technologies that followed this stage brought significant diversification and improvements in services. Today, there is more and more talk of the fifth generation of mobile communications technologies (5G). The security aspects of 5G networks are a hot topic worldwide, both among major state and nonstate actors. This article highlights the main characteristics of 5G technologies and why security of 5G networks is essential and complex."
