The auctions for the first 5G frequencies are launched on Tuesday, with the deployment of the first packages at the end of the year.

Guest from Europe 1, Guy Pujolle underlines the existence of a risk vis-à-vis data security.

For this international network specialist, Huawei could largely do well.

A considerable step forward for 5G will be taken on Tuesday, with the launch of the first auctions for the allocation of frequencies for this technology.

At the same time, debates continue to be fierce between supporters and opponents.

And according to Guy Pujolle, international specialist in networks, security is one of the themes on which these controversies are the most legitimate.

"For me, this is the point on which we could have discussions," he said at the microphone Europe 1 of Patrick Cohen, Monday.

Data, new oil

"It's an environment through which absolutely all data will pass," explains the computer scientist, author of

"Behind them, data centers will capture them and eventually use them."

And since "data is a bit like the oil of the 21st century", it is logical to see "whoever has a lot of data and who uses it earn a lot of money", recalls Guy Pujolle.

The specialist sees it "potentially a significant risk" in terms of data security at the global level.

Huawei in the heart of the storm

In this context where each country is trying to secure its telecommunications infrastructure, there is a manufacturer that has "a head start": Huawei.

The Chinese manufacturer has defined many standards and filed a large number of patents relating to this technology.

"The establishment of Huawei centers would allow China to recover these famous data", insists the computer scientist.

However, to paint a picture of a virtuous Western technology by nature in the face of necessarily pernicious Chinese technologies is not very relevant, explains Guy Pujolle: "All manufacturers without exception have back doors", he replies about too close proximity between Huawei and the Chinese state.

"Today, espionage is 90% American because it is American material. The Americans do not want to see their infrastructure replaced by Chinese material, which it is."
