Editor’s note:
No one doubts the upcoming change of 5G.
Internet of Things, Driverless, VR, Industry… The emerging technologies it has spawned are constantly refreshing people’s imagination of a better life in the future.
We would like to see this change as Thomas Kuhn’s “paradigm shift”: it still has a lot of immaturity, even less stability than the previous generation of technology, but in the long run, it is enough to promote scientific change and open a new chapter in communication, that is, to change the world.
People can’t help wondering: What is the advantage of 5G? What industries will it subvert? How does the fee change compared with 4G? What is the position of China 5G in the world?
On this occasion, Sina Technologies and Sina 5G Channel jointly launched the “5G Talk” series of video columns, inviting well-known people in the fields of politics, production, learning, research and use to interpret the development and landing of 5G in detail, in order to answer questions and puzzles for readers.

5G protocol is more secure but the hidden danger of multi-device networking
With the advent of 5G era, the network security problem is becoming more and more serious under the new situation.
Earlier, Wu He Quan, academician of the Chinese Academy of Engineering, admitted in an interview with Sina Technologies and Sina 5G that 5G security is a “double-edged sword” and will inevitably lead to new risks.
Zhou Hongyi, chairman and CEO of 360 Group, believes that 5G has the characteristics of fast speed and short delay. Industrial Internet, vehicle network, industrial Internet and so on will benefit, but it will certainly bring more security challenges.
Zheng Wenbin, known as the “driving prodigy” in the circle, is one of the top white hat hackers in China. At the age of 19, he was brought under Zhou Hongwei and devoted himself to the study of high-risk vulnerabilities. Entering the 5G era, enterprise security is one of his main tasks.
“I don’t think 5G itself will lead to more network security problems, but it may have some security risks of network vulnerabilities,” Zheng said. In terms of communication protocols alone, 5G is safer than 4G. It allows more devices to connect to the network at a faster speed, which will lead to more applications and scenarios. ” Use, scenarios and equipment will also bring more network security problems, and the increase of hidden dangers is an inevitable trend.
Inter-offensive and defensive forces in the network or more unbalanced
“For example, in the past, vehicles were partially networked, and the impact of network attacks was not so great, but after 5G, vehicle networking will have more functions and more applications, which will bring new security risks. In fact, it has brought more space for attackers and malicious attacks, “Zheng Wenbin pointed out.” Our country’s investment in network security industry and IT is far behind that of the United States. In the 5G era, we need to increase investment in order to better deal with network security issues.
Any 5G access device may become an intrusion point of network attack, which means that 5G will increase the potential targets of network attack. It is not difficult to imagine that the number of devices in the Internet of Things in the future is likely to be hundreds or even hundreds of times that of computers, which will also make the offensive and defensive forces of the whole network more unbalanced.
Smaller scale 5G of safety industry will play a promotive role
Previously, Zhou Hongzhen had publicly stated that the opponents of cyber warfare today are not individuals or institutions, but “countries and countries” contest, “more than 100 countries have established more than 200 cyber warfare units”. Under such circumstances, what is the status of Chinese security enterprises compared with other countries?
“I don’t think there is a big gap between the technology level of our security enterprises and the international level as a whole.” Zheng Wenbin believes that in the early years, many of our network security technicians turned to black production because of lack of job opportunities. With the rise of security enterprises, this situation has been significantly improved, “but compared with the United States and other countries.” For home, the scale of domestic network security industry is still at a low level, so it is an industry that needs to be developed urgently. The commercial use of 5G will play a great role in promoting the scale of the whole industry.
