A senior cyber security official stated that Huawei's "small" engineering practice means that its mobile network equipment may be banned from Westminster and other sensitive parts of the United Kingdom. The Chinese telecommunications giant also faced a ban on what he called the "brains" of 5G networks.
It is expected that the UK government will show in May whether it will restrict or even ban the technology of the company 5G.
Last month, GCHQ's security review said it was difficult to manage future Huawei products until defects in cybersecurity were fixed
. problems with the company's approach to software development have led to the vulnerability of existing products, which in some cases have not been corrected, despite the fact that they were identified in previous versions.
the head of the company's telecom equipment department, said he plans to spend more than $ 2 billion (£ 1
"We hope to turn this challenge into an opportunity to move forward," said Ryan Ding
"I believe that if we can carry out this program as planned, Huawei will become the strongest player in the field of telecommunications in terms of security and reliability."
"Very trivial & # 39;
Dr. Levy, Technical Director of the National Cybersecurity Center, GCHQ, said he had not yet been convinced.
"Security in Huawei is like the other one – it's engineering, like in 2000 – it's very, very tricky " We have seen nothing to give us any assurance that the transformation program will do what they they say that it will do. "
He added that" geographical constraints – probably no Huawei radio [equipment] in Westminster
Mobile UK, a branch group representing Vodafone, BT, O2 and Three, warned that preventing Huawei from participating in the British 5G deployment could cost the country's economy up to GBP 6.8 billion and delay the launch of next-generation networks to two  Those who are already using Huawei hardware have decided to leave it outside of what is called the core of their networks, which perform tasks such as checking device identifiers and defining voice and data transmission paths.
EE used the Huawei device in its 3G and 4G core, but now BT removes it after purchasing a business.
Industry, however, wants to use Huawei's (Ran) radio access network equipment – including antennas and base stations. They allow individual devices to wirelessly connect to mobile networks through radio signals transmitted over the radio.
In the United States there are concerns about any deployment of Huawei products.
"You will never know when the Chinese government decides to force Huawei … to do what will be in the interests of the Communist Party to overhear the United States," said Mike Conway, a member of the House of Intelligence Committee.
Last year, Republicans drafted a bill to ban the US government from doing business with firms using the company's equipment. Later he was adapted to become part of the National Defense Authorization Act, which was signed by law by President Trump.
This has led to the deterrence of the country's large telecommunication networks from working with Huawei.
Congressman now has his own views on Britain.
"Obviously, the stunning relationship between Britain and the United States – English-speaking countries –
"But as part of this, we will have to assess what risks we have in common use … the secrets that could go through Huawei's Huawei network equipment."
"We can always share the things of the old school way, knowing the paper there and back. But, from the point of view of electronic communication through the Huawei gear, the Huawei network, it would be risky at best. "
This issue crosses political differences.
Mark Warner, Democrat and Vice-Chairman The Senate Intelligence Committee also warned against allowing Huawei to be part of the UK's 5G networks.
"I think the consequences can be dramatic," he said.
tThe Levy GCHQ, however, has faced such fears that digital communication efforts mean that even if someone could intercept them, they would only have gobbledygook.
"Everything that is sensitive to a company or government or defense is independently encrypted by the network," he explained. You protect
He added that, despite the detection of vulnerabilities in some Huawei kits, "we do not believe that the things that we report are a consequence of Chinese state crimes." , Huawei says the Chinese government will never ask him to set backers or other vulnerabilities to their foreign customers' systems, and even if such a request is made, he will refuse.
And Mr Ding rejected the assumption that this commitment would fall into the background if the United States and China were to go to war.
"We have a country that practically does not use Huawei hardware and even does not know if our 5G equipment is square or round, and yet it is constantly expressing concern about Huawei security," he said.
"I do not want to speculate on whether they have other goals in this kind of conversation.
