Yesterday, the Global Encryption Coalition published a joint letter calling on the UK to rescind its demand that Apple undermine (“backdoor”) the end-to-end encryption on its services. The Internet Society is taking signatures until February 20.
The background: on February 7, Joseph Menn reported at the Washington Post (followed by Dominic Preston at The Verge) that in January the office of the Home Secretary sent Apple a technical capability notice under the Investigatory Powers Act (2018) ordering it to provide access to content that anyone anywhere in the world has uploaded to iCloud and encrypted with Apple’s Advanced Data Protection.
Technical capability notices are supposed to be secret. It’s a criminal offense to reveal that you’ve been sent one. Apple can’t even tell users that their data may be compromised. (This kind of thing is why people publish warrant canaries.) Menn notes that even if Apple withdraws ADP in the UK, British authorities will still demand access to encrypted data everywhere *else*. So it appears that if the Home Office doesn’t back down and Apple is unwilling to cripple its encryption, the company will either have to withdraw ADP across the world or exit the UK market entirely. At his Odds and Ends of History blog, James O’Malley calls the Uk’s demand stupid, counter-productive, and unworkable. At TechRadar, Chiara Castro asks who’s next, and quotes Big Brother Watch director Silkie Carlo: “unprecedented for a government in any democracy”.
When the UK first began demanding extraterritorial jurisdiction for its interception rules, most people wondered how the country thought it would be able to impose it. That was 11 years ago; it was one of the new powers codified in the Data Retention and Investigatory Powers Act (2014) and kept in its replacement, the IPA in 2016.
Governments haven’t changed – they’ve been trying to undermine strong encryption in the hands of the masses since 1991, when Phil Zinmmermann launched PGP – but the technology has, as Graham Smith recounted at Ars Technica in 2017. Smartphones are everywhere. People store their whole lives on them for everything and giant technology companies encrypt both the device itself and the cloud backups. Government demands have changed to reflect that, from focusing on the individual with key escrow and key lengths to focusing on the technology provider with client-side scanning, encrypted messaging (see also the EU) and now cloud storage.
At one time, a government could install a secret wiretap by making a deal with a legacy telco. The Internet’s proliferation of communications providers changed that for a while. During the resulting panic the US passed the Communications Assistance for Law Enforcement Act (1994), which requires Internet service providers and telecommunications companies to install wiretap-ready equipment – originally for telephone calls, later broadband and VOIP traffic as well.
This is where the UK government’s refusal to learn from others’ mistakes is staggering. Just four months ago, the US discovered Salt Typhoon, a giant Chinese hack into its core telecommunications networks that was specifically facilitated by…by…CALEA. To repeat: there is no such thing as a magic hole that only “good guys” can use. If you undermine everyone’s privacy and security to facilitate law enforcement, you will get an insecure world where everyone is vulnerable. The hack has led US authorities to promote encrypted messaging.
Joseph Cox’s recent book, Dark Wire touches on this. It’s a worked example of what law enforcement internationally can do if given open access to all messages criminals send across a network when they think they are operating in complete safety. Yes, the results were impressive: hundreds of arrests, dozens of tons of drugs seized, masses if firearms impounded. But, Cox writes, all that success was merely a rounding error in global drug trade. Universal loss of privacy and security versus a rounding error: it’s the definition of “disproportionate”.
It remains to be seen what Apple decides to do and whether we can trust what the company tells us. At his blog, Alec Muffett is collecting ongoing coverage of events. The Future of Privacy Forum celebrated Safer Internet Day, February 11, with an infographic showing how encryption protects children and teens.
But set aside for a moment all the usual arguments about encryption, which really haven’t changed in over 30 years because mathematical reality hasn’t.
In the wider context, Britain risks making itself a technological backwater. First, there’s the backdoored encryption demand, which threatens every encrypted service. Second, there’s the impact of the onrushing Online Safety Act, which comes into force in March. Ofcom, the regulator charged with enforcing it, is issuing thousands of pages of guidance that make it plain that only large platforms will have the resources to comply. Small sites, whether businesses, volunteer-run Fediverse instances, blogs, established communities, or web boards, will struggle even if Ofcom starts to do a better job of helping them understand their legal obligations. Many will likely either shut down or exit the UK, leaving the British Internet poorer and more isolated as a result. Ofcom seems to see this as success.
It’s not hard to predict the outcome if these laws converge in the worst possible timeline: a second Brexit, this one online.
