In an occasional paper which was described as not being an academic research document, Charles Parton of the Royal United Services Institute, said given that the US, Australia and New Zealand had acted against Huawei, "worries about the security of UK networks following their exposure to Huawei may make the Five Eyes partners, and perhaps others such as France, Germany or Japan, less inclined to co-operate with the UK in the future".
His remarks come in the wake of a report in the Financial Times that the UK's National Cyber Security Centre had concluded that any risk posed by Huawei to British networks could be managed.
Parton wrote: "The maintenance of a ‘Five Eyes standard’ of cyber security in telecommunications is a vital strategic and security interest, the loss of which would go far beyond a reduction in intelligence reports exchanged and might lead the UK being excluded from work on developing future technologies for intelligence collection."
Among its members are leading multinational defence companies, defence-related organisations, and government organisations.
In the paper, titled China-UK relations: where to draw the border between influence and interference, Parton cited a 2013 report from the Intelligence and Security Committee, which he said was scathing about Huawei's participation in current telecommunications.
"Among other criticisms, it pointed out that GCHQ could not be confident in finding insertions embedded in software containing over a million lines of code (or more, given frequent software updates), which would enable covert downloading of information," Parton said.
Huawei has already said that it is addressing these issues and the president of its Carrier Business Group, Ryan Ding, wrote to Norman Lamb, the chair of the House of Commons Science and Technology Committee, recently saying it would take between three and five years to fix these security concerns.
Parton said the UK should keep Chinese companies out of those parts of its critical national infrastructure "which would potentially give them access to data which might compromise national security, and from areas to which foreign companies are excluded in China, in particular, the telecommunications and power grid sectors".
He added that the UK should "maintain the same stance as the UK’s Five Eyes intelligence allies, particularly over 5G".
