Western governments seek to lock down 6G before it even exists

A group of Western governments has launched a fresh bid to shape 6G before it's even standardized, unveiling a set of security and resilience principles to bake supply chain controls and cyber safeguards into the next generation of mobile networks.

The announcement, made at Mobile World Congress (MWC) in Barcelona, marks the formal debut of the 6G Security and Resilience Principles under the Global Coalition on Telecoms, a bloc comprising the US, UK, Canada, Japan, and Australia, with Sweden and Finland now joining the club.

Nothing here is mandatory, but the coalition wants a say early. It argues that 6G will underpin too much of the economy to be treated casually, and says the security model can't simply be inherited from 4G and 5G.

The coalition flags the wider attack surface that comes with disaggregated architectures, heavier software layers, embedded AI functions, and integrated sensing features. It calls for stronger authentication, tighter controls around data integrity and confidentiality, and network designs that contain breaches rather than letting an intruder pivot freely across systems.

There's also an explicit push to consider quantum-resistant cryptography early, on the assumption that networks deployed in the 2030s will still be running when today's encryption standards start to look dated.

If this all sounds familiar, that's because it is. The same governments spent much of the 5G era scrambling to unwind dependencies on "high-risk vendors," reworking telecoms supply chains while networks were already live. This time, they're trying to get ahead of the curve, shaping technical standards and vendor behavior before 6G becomes commercially entrenched.

Industry, for its part, appears happy to nod along. Companies including Qualcomm, Nvidia, Ericsson, Nokia, Samsung, BT, Vodafone, and others voiced support for the principles, at least in broad terms. That endorsement comes amid a wider marketing push at MWC, positioning 6G as "AI-native" from the outset.

Only yesterday, Qualcomm and Nvidia were touting plans to build next-generation wireless networks around tightly integrated AI and software-defined platforms, despite the absence of finalized 6G specs.

So while vendors are busy selling 6G as AI-native, it seems governments are quietly reminding them that "AI everywhere" also means "risk everywhere."

Still, the principles stop well short of binding commitments. There are no enforcement mechanisms, no new procurement rules, and no immediate penalties for vendors that choose to chart their own path. Instead, the coalition is betting that coordinated messaging from a cluster of major telecoms markets will influence standards bodies and commercial roadmaps.

For now, 6G exists more in research papers than in racks of equipment. That makes it easier for policymakers to try to influence the direction of travel before networks are locked in and retrofits become the only option. ®
