THE next generation of mobile communication needs to tighten security if it is to offer customers a safe and reliable service, according to a study by a team of international researchers.
The team, which includes an academic from the University of Dundee, is questioning whether 5G mobile communication standard will be robust enough in its current form.
Two-thirds of the world’s population use smartphones on a daily basis, connected across the planet by the mobile network. For mobile providers, the business is worth billions.

But it has also proved a fertile hunting ground for criminals who have been able to access the communication between a device and a network in order to intercept conversations or steal data.
The research team from the ETH Zurich, the University of Lorraine/INRIA and the University of Dundee, subjected 5G mobile to a comprehensive security analysis, finding that while data protection has improved on that offered in the 3G and 4G versions, critical security gaps remain.
Dr Saša Radomirovic, senior lecturer in the School of Computing at the University of Dundee said: “People will use 5G like they use 4G now, to make calls, send texts, swap pictures, or make payments and purchases.
“But 5G will likely also be present in autonomous vehicles, Internet of Things devices, and industrial control systems, for example. It has been promised to be faster and more secure than previous networks but we’ve found that it isn’t as secure as hoped.
“In its current state, 5G does not close all the security gaps, which could result in numerous cyber-attacks and users being charged for the mobile phone usage of a third party. We have proposed a number of improvements to close these gaps.

“What we remain concerned about are the less than perfect privacy protections it provides leaving users vulnerable to targeted attacks.
“The most important takeaway from our work is that introducing a new technology without a rigorous formal analysis of its specifications may lead to serious consequences. Our formal verification methods and our Tamarin prover tool can help prevent that.”

Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
Callum Baird, Editor of The National
