Meredith Whittaker Reaffirms That Signal Would Leave UK If Forced By Privacy Bill (techcrunch.com) 69

Meredith Whittaker, the president of the Signal Foundation, which maintains the nonprofit Signal messaging app, reaffirmed that Signal would leave the U.K. if the country's recently passed Online Safety Bill forced Signal to build "backdoors" into its end-to-end encryption. From a report: "We would leave the U.K. or any jurisdiction if it came down to the choice between backdooring our encryption and betraying the people who count on us for privacy, or leaving," Whittaker said. "And that's never not true." The Online Safety Bill, which was passed into law in September, includes a clause -- clause 122 -- that, depending on how it's interpreted, could allow the U.K.'s communications regulator, Ofcom, to break the encryption of apps and services under the guise of making sure illegal material such as child sexual exploitation and abuse content is removed.

Ofcom could fine companies not in compliance up to $22.28 million, or 10% of their global annual revenue, under the bill -- whichever is greater. Whittaker didn't mince words in airing her fears about the Online Safety Bill's implications. "We're not about political stunts, so we're not going to just pick up our toys and go home to, like, show the bad U.K. they're being mean," she said. "We're really worried about people in the U.K. who would live under a surveillance regime like the one that seems to be teased by the Home Office and others in the U.K."

    • Criminal gangs are already doing criminal things. They are committing bigger crimes than running an "illegal" service on their computers. If you plan to rob a bank, do you care about the parking ticket your getaway car might get for standing in the no-parking zone?

      • The idea, for criminal gangs, is to avoid detection so not quite like robbing a bank. They want to plot, plan, collude, etc., at a distance in secret so that law enforcement is less able to build prosecutable cases against them. That's the point of wire taps & what this law is designed to enable. However, doing it without a warrant also enables politically motivated surveillance (what MI5 is most famous for) that isn't usually legal & definitely not moral.

          The law leaves itup to Ofcom to decide who must comply. If Ofcom never asks, signal doesn't need to do anything. If it does, they can leave or challenge it in court. If the court says they must comply, then they will leave since compliance is out of the question.

          The Parliament has opened a huge can of worms for themselves. Ofcom could do them a favor by never asking so the law joins the ranks of kooky laws that are never enforced or they can press the issue and let Parliament catch the eggs with their faces.

          Meanwhile, in the unlikely case that Signal has any offices in the U.K. now is the time to close them.

          At the end of the day, if asked and affirmed by the court, it's unclear what the government could do if Signal has no business presence in the U.K., especially if they officially state that U.K. citizens are not to use the app. People will anyway, of course, but the law doesn't actually make that illegal. That's where the egg on the face comes in.

          At the end of the day, compliance is not even technically possible. End to end encryption prevents even signal from reading the messages. The app is Free Software, so they can't just sneak a back door in without it being quickly found and removed even if they were stupid enough to try (they aren't).

          That is best for Signal as well as it's users. If they had the technical ability to share the messages with law enforcement they would be continuously bombarded with requests from every Barney Fife that fancies himself to be the next Eliot Ness.

    For two reasons, session is superior to signal. Primarily is also secure and verified original user, but also anonymous. Too many people try to break security and privacy into two separate things. But they are very closely related and you can not truly have security without also being able to be anonymous if you choose. The fact that signal ties the account to a phone number which is usually tied to a real person or can easily be tied to real person is not acceptable. Two people need to be able to verify that the people that exchange credentials are truly each other after that initial exchange, but they do not need to able to expose the real world identity of the other party if that party chooses not to exposed. Many times it is important that two parties trust the communication between each other but due to circumstances need the security of ensuring that neither side, nor the company creating the software, nor the carriers delivering the traffic can easily work out who the real person is behind the communication.

    • verified original user, but also anonymous

      That's an oxymoron: you can't be both verified and anonymous.

      • It can be, depending on what you mean by anonymous. If you mean that nobody can tell where a message comes from then you're right. When your goal is just to not have any real life names and information attached to it, you're essentially at what registered users are here to the readers. De-facto anonymous, but at the same time you can easily verify whether something was posted by me.

      • Suppose you have a load of messages, all of which are signed by the same private key. For each message, this gives good verification of it being by the person who posted all those other messages. And yet they can still be anonymous in that nobody can tie these messages to a real-world identity. You can't just be verified and anonymous with regard to the exact same detail. "Verified to be Sarah Burns of 321 Lancaster Road, Banbury" (made up name and address) and "anonymous real-world identity" is impossible
    • For that you use a throw away SIM, and you are done.

    • but also anonymous

      This is the least desirable feature of a messaging service used for anything other than nefarious activity.

    • ... two parties trust the communication ...

      There are 2 types of channels of communication: Knowing who is talking to whom (most electric/cyber technology) and the dead-drop (where the parties can't identify each other). The dead-drop brings complications to speed, reliability and size, so address-based communication is preferred. Since all addresses are owned, there can never be anonymity: Many 2FA services use that fact as proof of identity.

    • Session is inferior to Signal in that I managed to get loads of ordinary people (those who count to me) to use Signal, and others tell me of likewise situations. The phone number point is relevant to a disappearingly small percentage of the population, and the other relevant big players , WhatsApp and Telegram, also require a mobile number.

    Imagine your government has access to a backdoor to encryption and can break any encryption. This in turn means that someone has to have access to those keys.

    Now imagine someone scooting up to the government agent who has those keys and says things like "You have a nice wife. And really beautiful children. Shame if anything happened to them. Real shame. But you know what, let me have those keys. Don't worry, I won't tell anyone. And your beautiful wife and lovely kids can continue to live".

    And if he doesn't comply, he'll be made the example for the next guy getting that offer with a "I heard what happened to your colleague, really terrible that accident. Now I noticed you have a nice wife and some beautiful children, too..."

    You think those keys will remain secret for long? Please don't be so naive.

      Indeed. Also remember that even the mighty NSA had malware stolen from them a few years back and that Microsoft had a cloud master key (i.e. "crown jewel") stolen from them due to sheer incompetence this year. There is no way to make a system that is connected to the Internet and needs to communicate with lots of other systems hack-proof these days. And then the criminals have that backdoor access too.

          Theoretically? Yes. Or at least you can come very close by reducing input interfaces dramatically. I once did a mini-study where the only outside connectivity was via serial interface using the rather small Linux serial driver and a very restricted protocol and an otherwise passive MCU watching over the protocol being kept and cutting the connection otherwise. With such a set-up you get a very low residual probability of attackable vulnerabilities being left and even hardware backdoors can be prevented as l

      Exactly this. Government is not some magical entity. It is composed of people. Some good, some evil, most just trying to get through the day. Those people will have access to the backdoor. They will get phished. The evil ones will spy on people they don't like. Politicians will want dirt on their rivals. Whatever.

      Why do that? Threats may be met by getting law enforcement involved. Cash or blackmail is better. "wouldn't you like to have a nice retirement fund?" or "You know those two hotties you were with last night. Be a shame if your wife found out by watching this video..."That also has teh advantage of making them a willing accomplice or with something to hide, so they are more likely to not turn you in.
