back to article Here we go again... UK Prime Minister urges nerds to come up with magic crypto backdoors

UK Prime Minister Theresa May has reiterated calls for a special magic version of encryption to be developed by technologists so law enforcement can access everyone's communications on demand – and somehow engineer it so that no one else can abuse this backdoor. Speaking at the World Economic Forum (WEF) in Davos, Switzerland …

    You want a back door?

    Best thing you can have to a backdoor would be for all the western nations to chip in a build a colossal supercomputer and just brute force the encryption. You know what's great about this? Only nation-states could ever use such a method, cause I don't think there are enough grains of sand to make a computer that big once, let alone twice.

      Hah yes. Charge one bitcoin per decrypt request. That'll increasingly tie their supercomputers up for longer and longer. Or provide them with a reason to confiscate - sorry I mean 'asset forfeit' peoples Bitcoins.

      In addition, it would be so expensive in terms of computing power that it would only be used to decrypt stuff that the security services strongly believe contains vital information. No way that everyone's private coms could be routinely decrypted and scanned for keywords.

      Don't laugh. This may actually exist. There's that huge data center in Utah. Could actually be a cover for a black-project working quantum computer breaking messages using Shor's Algorithm.

    Good you included Wyden

    It was an epic slam-down and you should have quoted it more fully, actually.Here's a little more


    Wyden blasts FBI chief over encryption remarks

    © Camille Fine

    A Democratic senator is blasting the leader of the FBI over recent comments he made about encryption, calling them “ill-informed.”

    Sen. Ron Wyden (D-Ore.) wrote a letter to FBI Director Christopher Wray on Thursday criticizing him for advocating for a technological solution to what is often referred to as the “going dark” problem: the inability of officials to access data on encrypted devices for ongoing investigations.

    Wray said during recent remarks that devices could be designed “that both provide data security and permit lawful access with a court order.” He also dismissed the idea that law enforcement investigators are looking for some kind of “back door” into encrypted devices.

    In his letter Thursday, Wyden slammed the suggestion, saying that it would inevitably degrade the security of the devices themselves.

    “Regardless of whether the Federal Bureau of Investigation labels vulnerability by design a backdoor, a front door, or a ‘secure golden key,’ it is a flawed policy that would harm American security, liberty, and our economy,” Wyden wrote.

    Wray made the remarks at a conference in New York earlier this month, during which he described the bureau’s inability to access encrypted communications as a “major public safety issue."

    According to Wray, the bureau was unable to access digital content of nearly 7,800 devices for investigations last fiscal year despite having the “legal authority” to do so.

    “If we can develop driverless cars that safely give the blind and disabled the independence to transport themselves, if we can establish entire computer-generated virtual worlds to safely take entertainment and education to the next level, surely we should be able to design devices that both provide data security and permit lawful access with a court order,” Wray said.

    “We’re not looking for a ‘back door’ — which I understand to mean some type of secret, insecure means of access,” Wray added. “What we’re asking for is the ability to access the device once we’ve obtained a warrant from an independent judge, who has said we have probable cause.”

    On Thursday, Wyden countered that designing such a proposal that still preserves security would be impossible.

    “Experts are unified in their opinion that introducing deliberate vulnerabilities would likely create catastrophic unintended consequences that could debilitate software functionality and security entirely,” he wrote.

    Wyden asked Wray to provide a list of cryptographers he has consulted with to arrive at his proposal. "

    Because the list would be zero-length of credible cryptographers.

    What they want is for there to be no end-to-end encryption and have companies (ie, customers) pay to store it all along with the keys so they can get it with a warrant. Of course, online CC and banking would be exempt, because they are already in the palm of their hands and will willingly (or not) give the feds all records (this problem is described in a fun way in the "stainless steel rat" scifi series, harry harrison, not great scifi but fun).

    But the real reason the extension passed isn't because we didn't harass our congress swamp critters, it's because the very first snooping was to get the dirt on them to get votes to go the 5-eyes way every single time - no exceptions, even for show - name one, I dare you. It's the dog that didn't bark.

    Really, what does anyone suspect. That pols are clean? Don't we know better, much better? Who cares if my personal habits come out - not me, but if I was a pol fishing for re-election, then I care, eg, the MAIN targets of blackmail are the pols - the guys who sign the paychecks of the 5 eyes. Even if you were a brain-dead beaurocrat, who would you get the dirt on first? Meaningless citizens or people involved with "national security" or - keeping your rice bowl full. Occam's razor.

      Apart from the fact, as pointed out, we can't actually do those things, even if we could it would be a terrible argument, apples aren't oranges.

    Once upon a time...

    In a land not too far away law enforcement officials couldn't eavesdrop on the dastardly plans of criminals unless the could personally overhear what was being said.

    It seems to me that those times have simply returned and attempting to remove the privacy that we previously could assume is no longer possible.

    Big brother simply needs to understand that (or possibly put Siri/Alexa etc. to listening to every inch of the planet).

      There's potential in reversing this approach. HMG puts its money where its mouth is and offers a contract to build this system they believe could be built. The usual suspects will tender and one of them will get it. They will fail to deliver but that's true of many govt. contracts. Unlike the others this won't be wasted money. It'll be money well spent on shutting the idiots up while they wait for something to be delivered. Hopefully those on the relevant Parliamentary committees who twig what it's about will keep schtum.

      I honestly think we seriously underestimate our politicians if we think they don't know how stupid are the things they say. The things they say aren't intended for people who know better. The words are for people who do not understand the subject but think they know enough. For any given subject, encryption, economics, climate change, whatever, the sub set of those who know little if anything vastly outnumbers the subset who do know something and hence has greater positive effect for the politician if it sounds like they are saying the right thing. Us being cynical and calling them stupid tends to drive us away from participation in politics and voting and works in the favour of those who would rule us. Everything they say has a specific target audience and, generally, is carefully formulated.

      We underestimate them at our own peril.

    M of N Secret Sharing

    It sounds like they want a modified M of N scheme. The individual would only need one secret to access the plain text, while law enforcement would need N secrets to access the plaintext. Thus, the number of secrets would have to be gathered from a number of bodies via warrant, protecting the individual.

    But of course that wouldn't prevent other solid encryption algorithms from being used.

      I could actually see something like that working for proprietary apps, and honestly I wouldn't really care -- proprietary apps have far more backdoors than a mandated M+N scheme would provide.

      Hello phone, some new judges have been appointed. Here are their public keys. Did I accidently put my key in the list?

      I wish I could find the video I saw of an old judge explaining some aspect of technology. I cannot tell you what sort of technology he was explaining because he kept getting stuck half way through sentences and forgetting what he was talking about. After about quarter of an hour, I could not stand to watch more. Not all judges are senile (although that does seem to be a popular career move in the US). There is even a judge who understands every single line of code Google copied from Java. Such judges are rare. I have met "techies" without the brains to understand what a secret key is, and PHBs with the computer literacy to keep a secret key secret are few and far between.

      Giving each judge a secret key is as sane as giving each employee a four digit access code (someone will pick 1066).

    I keep wondering if there is any messaging application that a) does not store even encrypted contents or metadata after delivery (or timeout), b) encrypts the contents and the recipient's details between the sender and the server with a one-time key shared with the sender, c) introduces a random delay to thwart correlation analysis, d) pads the contents to prevent tracking by size (may be superfluous with encryption, but let's keep it in the list), e) re-encrypts the contents and the sender's details with a one-time key shared with the recipient, f) does not keep either the plain text or the encrypted content or the one-time keys or any logs after delivery, g) by default disallow (if possible) synching/backing up to "the cloud".

    This will make it so much more difficult for the alphabet (isn't there a company called that?) soup agencies to do metadata analysis. Their remaining options will be restricted to intercepting at the server (or MITM to fake the key exchange), and that will hopefully be restricted to the provider's country of origin and will not give them access to the past history for at-will exploration.

    Most of all, I wonder if there may be a business case for such a system (beyond being financed by the next OBL). Not obvious, given that it will be more complex, presumably more expensive to operate, possibly somewhat more cumbersome to use than WhatsApp.

    1. Graham Cobb

      Re: Metadata

      Bitmessage had some of those attributes. Its big downside was that it didn't scale as it effectively broadcast every message to every recipient as it has no idea who the destination was (if you could decrypt the message you must be the intended recipient).

      I don't know if the bitmessage network is still running. It was an interesting experiment.

    Licensing of Operators

    There is no sanely manageable way to have encryption with a magic back door.

    So this is all headed ultimately in the direction of licensing, just like telcos are licensed. You want to offer a service and collect revenue? Gonna have to respond to warrants or have your revenue streams cut off at source and your domains blocked.

    The Chinese have their great firewall. Everyone else is headed that way too eventually so that they can wield that kind of stick.

    1. Graham Cobb

      Re: Licensing of Operators

      Except that the bad guys (terrorist groups, mafia, etc) have no need of collecting revenues for the service. So, they don't need a licence.

      So, as always, the proposed restrictions just prevent safety for good guys and leave the bad guys untouched.

    And that Genie ...

    The ignorance and stupidity of politicians aside, I return to the Genie—who cannot be returned to the bottle. Even if every mainstream encryption app could be compromised somehow (and therefore would no longer be used by anyone, of course), you cannot un-make the mathematical knowledge and algorithmic techniques to execute seriously tough encryption. There is basically nothing to stop any competent programmer knocking up some code, in almost any language, to encrypt data on a device. It's pretty unlikely that even quantum computing will be decrypting today's best encryption if executed properly with sizeable keys (and since the "imminent apocalyptic terrorist attack" bullshit so beloved of imbeciles who watched too much 24 is the usual inane justification, even decrypting the data as quickly as a month later is of little use).

    Add good stegnogaphy*¹ to the mix and it is just moronic to think that serious bad actors will be much hampered by prohibiting e2e encryption apps—even if you could.

    So why do the security services keep misleading gullible politicians? For they must know (a) that they are lying about backdoors, yet (b) keep on lying anyway.

    I can only assume that aside from the usual empire-building budget-tumescing nonsense beloved of such people, this is about sheer laziness. The hard slog of humint, infiltration, shoe-leather intel gathering, hearts-and-minds ops, training and employing enough translators, learning about other regions' cultures and habits, using diplomacy and softpower to get what you want—perhaps it's all too difficult, when you delude yourseelf into believing that the computer can do it all for you? I do wonder what degree of self-delusion goes on in places like Babylon on Thames ... and perhaps more so at places like Langley. Judging by the apparently rotten advice they give to the political nincompoops, perhaps they are neither as realistic nor as practical as we'd imagine.
