The EARN IT Act is an Attack on Encryption (cryptographyengineering.com) 176

A bipartisan pair of US senators on Thursday introduced long-rumored legislation known as the EARN IT Act. The bill is meant to combat child sexual exploitation online, but if passed, it could hurt encryption as we know it. Matthew Green, a cryptographer and professor at Johns Hopkins University, writes: Because the Department of Justice has largely failed in its mission to convince the public that tech firms should stop using end-to-end encryption, it's decided to try a different tack. Instead of demanding that tech firms provide access to messages only in serious criminal circumstances and with a warrant, the DoJ and backers in Congress have decided to leverage concern around the distribution of child pornography, also known as child sexual abuse material, or CSAM. [...] End-to-end encryption systems make CSAM scanning more challenging: this is because photo scanning systems are essentially a form of mass surveillance -- one that's deployed for a good cause -- and end-to-end encryption is explicitly designed to prevent mass surveillance. So photo scanning while also allowing encryption is a fundamentally hard problem, one that providers don't yet know how to solve.

All of this brings us to EARN IT. The new bill, out of Lindsey Graham's Judiciary committee, is designed to force providers to either solve the encryption-while-scanning problem, or stop using encryption entirely. And given that we don't yet know how to solve the problem -- and the techniques to do it are basically at the research stage of R&D -- it's likely that "stop using encryption" is really the preferred goal. EARN IT works by revoking a type of liability called Section 230 that makes it possible for providers to operate on the Internet, by preventing the provider for being held responsible for what their customers do on a platform like Facebook. The new bill would make it financially impossible for providers like WhatsApp and Apple to operate services unless they conduct "best practices" for scanning their systems for CSAM. Since there are no "best practices" in existence, and the techniques for doing this while preserving privacy are completely unknown, the bill creates a government-appointed committee that will tell technology providers what technology they have to use. The specific nature of the committee is byzantine and described within the bill itself. Needless to say, the makeup of the committee, which can include as few as zero data security experts, ensures that end-to-end encryption will almost certainly not be considered a best practice.

Child exploitation is a scourge on our society, but stopping isn't isn't worth the price of losing our rights to privacy to talk amongst each other. It's just not. There. Said it. The ends don't justify the means in this case. We can't end every freedom we've fought for in the name of ending child exploitation.

            It goes even farther: The last time this was discussed in Germany, the national association of those abused as children was very much opposed to the law and found it pretty vile that their suffering was used to justify it.

            The other problem is that this will not stop a thing. People trading this stuff will just step up their security. And it is the wrong target anyways. Obviously, most child abuse is not recorded.

            Hell no. Lock them away where they can't do any harm, sure. If you want to then go above that to be actively cruel, then you're just getting your jollies. Civilized countries have banned cruel punishments in law, even if the US seems to ignore that part of the constitution the ban is still there.

            • The Supreme Court has made it clear that the "and" in "cruel and unusual punishment" is important. You can punish people in unusual ways if it's not cruel. Some judges use this leeway to attempt to deliver better outcomes. You can also punish people in cruel, traditional ways. Hence capital punishment and other forms of punishment that are generally accepted, such as the dehumanizing impact of prisons.

          From TFA:

          The risk of liability isn’t likely to kill encryption or end internet security. More likely, it will encourage companies to choose designs that minimize the harm that encryption can cause to exploited kids. Instead of making loud public arguments about the impossibility of squaring strong encryption with public safety, their executives will have to quietly ask their engineers to minimize the harm to children while still providing good security to customers—because harm to children will in the long run be a cost the company bears.

          The whole thing is a moronic argument to justify frightening companies into NOT offering end-to-end encryption.

          It's worth noting that even *IF* you were to give the government every benefit of the doubt, assuming their motives and all of their activities were nothing but benign (I know that's a stretch, but hear me out), it follows because of fact that you cannot stop people from being able to do math (and all computation is ultimately math), that if the government can access your private data, then so can any potentially malicious actor. It's important to realize that this is not just pessimistic speculation, it's actually a foregone conclusion.

          This means that rather than being able to access your private information resulting in the government's improved ability to crack down on illegal activity, law enforcement's job is actually made *harder* and not easier, because now they would additionally have to protect innocent people from exploitation by bad actors who are reading the same information that the government has access to.

          Of course, that's still assuming that the government has the genuine intent of trying to stop criminals in the first place.

          I am genuinely curious what a proponent of this kind of bill would have to say when they are forced to confront this enormous corner they are trying to paint themselves and everyone else into.

          I can't think of any response that a proponent might give that wouldn't be an outright and obvious admission that they actually don't care about the safety or security of the general public at all.

            Firewalls [CBR03], packet filters, intrusion detection systems, and the like often have difficulty distinguishing between packets that have malicious intent and those that are merely unusual. The problem is that making such determinations is hard. To solve this problem, we define a security flag, known as the "evil" bit, in the IPv4 [RFC791] header. Benign packets have this bit set to 0; those that are used for an attack will have the bit set to 1.

Google clearly has technology like this that they use for their image search functionality (it's effective even on images that have been cropped or recolored) but I'm not aware of any open solution that can do the same thing. Still, it's a much better idea for solving the problem than just about any other option I've seen mentioned.

    The National Center for Missing and Exploited Children officially supports the EARN-IT Act [missingkids.org]. For whatever that's worth.

    NCMEC official statement on end-to-end encryption [missingkids.org]: "Over the past 20 years, we’ve received more than 55 million reports of child sexual abuse to our CyberTipline - in 2018 alone we received over 18 million reports. The abuse is graphic and violent, and the sharing of images online drives the market for offenders to create more images and abuse hundreds of thousands of children each year."

    So, basically what they're saying is that whatever they're doing now is completely useless and ineffective, but somehow encryption makes the problem worse.

    "If end-to-end encryption is implemented without a solution in place to safeguard children, NCMEC estimates that more than half of its CyberTipline reports will vanish." Well, now I kinda want to see the law passed, just to find out how accurate their prediction turns out to be. And if the number of reports dropped from 18 million to 9 million, how would that affect the number of criminal cases actually prosecuted?

      No matter how many liberties they take away and how much they spy on people by putting everyone under the blanket of suspicioun, it's never seems to be enough. Shit still happens and even appears to be getting worse if we look at the current racist extremism in Germany for example. Now there's an entirely new thing to be afraid of - a large dark figure of far-right extremism that has somehow gone unnoticed and is growing despite all the domestic spying that is already done. So what's to be done about that?
      Their answer appears to be always along the same lines: we're not spying enough. More will fix this.


      Hence I'd expect that would be a dangerous step to satisfy one's curiosity as things are not likely to change that much except that the erosion of freedoms progressed one step further to widespread acceptance.

        Isn't this related a key vs a combination lock? The law can compel you to give a key if it exists but can't compel you to reveal what you know based on the 5th amendment. So the government has the right to get the locked data and the right to try and break it but no guarantee of success.

        I don't see how all of us giving up our rights to secure communication for personal and business reasons is possibly worth it just so the government has an easier time of finding people breaking the law.

        Remember all of this was in RESPONSE to the government. We got end to end encryption because the government was performing warrantless mass surveillance. This was done because the government was abusing our privacy and the companies responded to that.

  • "platform like Facebook" "force providers to either solve the encryption-while-scanning problem, or stop using encryption entirely"

    Not much more one can say after reading this. So let the laughing commence ;) lol

    Just my 2 cents ;)
  • ... only outlaws will have encryption.

    Maybe these morons like Lindsey Graham should try almost ANY modern transaction without encryption and see how fucking clueless they are when their account is hacked because you just made it (almost) trivial to get hacked.

    Anytime a politician uses the excuse Think of the Children they almost ALWAYS have a secondary agenda. They have to piggyback it on a rider bill because no one would go for their half-baked bullshit idea by itself.

  • That's a particularly disturbing name for a CSAM-based bill given how many politicians were associated with Epstein.
  • I can't wait for someone to slurp up Lindsey Graham accessing his bank account or preferred porn sites.

  • That is just a convenient pretext. Attacks on encryption have traditionally been justified with any of the "Four Horsemen of the Infocalypse". This is no different, except that it is even more despicable because it exploits abused children again.

    The real motivation behind this is and has always been preventing citizens from being able to communicate online without needing to fear that the government is listening. The threat of listening serves to a) create chilling effects where people self-censor (just lik

  • Perhaps the proper answer to "child porn" should be: "well, perhaps people should keep better track of their children".

    Then, when it gets pointed out that it's offensive to good parents whose children were abused, point out that banning cryptography or breaking it by forcing installed backdoors is actually equally offensive.

Heard that the next Space Shuttle is supposed to carry several Guernsey cows? It's gonna be the herd shot 'round the world.
