I disagree with the conclusion of absolute security — it won’t happen, and only encourages subversion by people who both need and have a right to access the content.

Instead of pontificating, the tech industry should innovate.

There’s no reason that hashchains can’t be used to timelock the key, and the enclave export it in response to a signed request. Then we can at least force the compromises through the legal system and require effort to reverse the hashchain. That kind of court authorized targeted access removes the incentive (and justification) for other actors to more deeply compromise the system. In turn, this let’s us provide more security, in practice.

What’s not going to sell, and what the tech industry needs to get over is “lulz, it’ll impossible to intercept military or terrorist information because I need absolute privacy for my saucy emails”. I think it’s been empirically demonstrated that won’t happen.

Be part of the solution.

Seems to be an ironic mischaracterisation of the parent’s point, which was precisely that one coubtry’s terrorism is another’s gay rights activist or high ranking foreign official.

From the article:

In 2017, for instance, the operatives used Karma to hack an iPhone used by Qatar’s Emir Sheikh Tamim bin Hamad al-Thani, as well as the devices of Turkey’s former Deputy Prime Minister Mehmet Şimşek, and Oman’s head of foreign affairs, Yusuf bin Alawi bin Abdullah. It isn’t clear what material was taken from their devices.

“Saucy e-mails” is a bit tone deaf :(

My point was that issues like this should be mediated by courts and existing legal systems, not the unilateral decision of technologists.

And that society is going to insist that be the case, hence the most effective way to protect those persecuted minorities is via cooperation and steering how that process happens — not fighting a losing battle.

Finally, that the way to increase the effective security is stop fighting ideological battles on the issue, and find a politically workable compromise which still prevents remote exploitation — the main danger of encryption bypasses.

Are you forgetting that time that the spy agency collected call records on millions of Americans through a secret court? [1]

As the other commenter points out, this only adds an attack vector and does not do anything to eliminate any.

The same incentives exist on all sides to find exploits regardless of an additional “legal” channel to crack the encryption. Particularly because your political enemies use the same devices and you can’t get a court order to tap their phones (usually).

It does not, but it changes the set of people looking to buy them and the way in which they’re used, both of which impact the general market for vulnerability sales — and additionally, re-aligns some present attackers to defenders.

Security researchers, strangely enough, seem to care who they sell to. If the NSA stopped buying and only the UAE was interested, I expect we’d see some firms move to other business models or targets for “research”.

Wouldn't the police have a "right" to know if a person has any weapons? Detaining everyone and performing a full cavity search for any and all infractions is just the police exercising their "right" to such information.

I wonder if that maxim is still generally approved. It seems like some authoritarians would prefer that 100 innocents would suffer than one guilty person should escape.

I suppose it depends how you define "innocent" and "suffer". Under modern law, everyone is guilty of something. And while we might not require suffering in prison, a little suffering of expensive legal fees, invasions of privacy of your digital data/at the border/in the airport, or searches and seizures of property by police in your car are commonplace.

>Under modern law, everyone is guilty of something.

This is a really dangerous (and unfortunately oft-repeated) mindset that basically boils down to advocating the position of "current laws are so complex that if we give law enforcement better tools [to combat law breaking], we'd implicate ourselves also".

This ignores two huge problems:

1. No, not everyone is guilty of something. I doubt a majority are guilty of anything, and I'd be surprised to hear even like 10-15% are guilty of anything.

2. The people that _are_ guilty of some minor infraction (e.g. jaywalking, speeding, or pick your own obscure state law) are still guilty of much less than the major crimes these kinds of systems are targeted at (terrorism, violent crime, robbery, etc). Comparing the two is like saying "we shouldn't put cameras at bank entrances because what if it catches someone jaywalking outside?"

On a more hard-line note, the people that are guilty of even the smallest things are still guilty of those things. People speed because they think they won't get caught, but it's still against the law. People jaywalk because they think they'll be safe crossing the street, but it's still illegal. People litter because they think it's not a big deal, but it's still illegal. Who gets to decide what people should get away with? Why would anyone be able to get away with breaking any law? (To wit, the obvious response is that some laws are obscure and outdated and that people aren't even aware of them, but feel free to refer back to #2 above until we've fixed those laws. Perhaps actually enforcing them is the nudge we need to push lawmakers into saying, "You know those crazy laws that are still in the books that we've ignored for a hundred years? Yeah, maybe we should get rid of those.")

>That it is better 100 guilty Persons should escape than that one innocent Person should suffer

This maxim encourages a false dichotomy that is embraced by the "we're all guilty of something" mindset, and forgets that "suffering" is a spectrum.

The people who are guilty of gotcha laws _aren't_ innocent, and _should_ suffer proportionately to the law they broke (see: fines, warnings, etc that you'd expect for silly laws that people think shouldn't be enforced, yet are still laws). I'd much rather see that "innocent" person get their $50 fine so 100 people guilty of violent crime don't escape.

"It is better 100 guilty [murderers] should escape than that one innocent [jaywalker] should suffer." Sounds silly, doesn't it?

Re:'Karma': A hack used by the UAE to break into iPhones of ... by basilgohar on Wednesday January 30, 2019 @04:38PM (#19039814)
Totalitarianism and police states don't start by jailing the jaywalkers, but they do start by implementing the laws disproportionately against marginalized communities within the general population. This is generally overlooked by the remainder because they think, "Well, it's not affecting me."

The problem with this line of thinking, "they broke the law, they should be punished whatever it was" is that laws and morality, while sometimes intended to be aligned, are not.

Take, for example, "disobeying a police officer". On the surface of it, no one would argue that that is a problem, thinking, "of course I'll follow a police officer's instructions". However, the system has evolved to the point where someone who has initially committed no crime, stopped by the police under suspicion, can end-up dead or incarcerated due to a sadly more-and-more common sequence of escalations.

Asserting that the law is somehow perfect to the extent that all illegal behavior should be punished is also poorly framed because not everything is illegal everywhere, and in fact, what is legal and illegal is not universally known or clear. For example, to access some laws in some municipalities, the laws themselves are under private copyright and a fee must be paid and they are not accessible except directly in person, as in, not remotely (this was news a while back, not sure if there's a HN story about it).

So, I feel this viewpoint is missing some fundamental realities that may drastically change the underlying assumptions.

It is not fundamentally true nor universally accepted. Where does the scale tip? All criminal justice systems attempt to minimise the risk - but one some level it is simply the cost of doing business. For all that it is an admirable sentiment, it is limited.

Uh, my proposed solution required getting a warrant to order a company to produce a device specific message which in turn could be provided via cable to the physical device, which they must also have access to, followed by spending time reversing a hash chain.

So yes, the police already have the power to search you for weapons if they have a warrant, and this is bringing the ability to search phones into line with that.

Re:'Karma': A hack used by the UAE to break into iPhones of ... by FakeComments on Wednesday January 30, 2019 @11:03AM (#19036165)
That’s a deep straw man of what I said, to the point of being non-constructive mocking. You’re just being dishonest to claim I suggested trusting the spy agencies.

Rather, I pointed out that they have a real mission, and they’re going to spend effort accomplishing it. But their mission isn’t to own every device — it’s to own a select few, probably on the order of hundreds or thousands a year. So, if we create a mechanism by which they can do that without owning every device, we can align our goal of protecting most devices with theirs of owning a few.

This in turn increases security for nearly everyone, because powerful agencies no longer have the same motivation to cause harm — and might be persuaded to help. After all, it’s in their interest to prevent large remote compromises — just not a higher priority than maintaining their own access.

Further, the best way to actually restrain them is through a change in government policy, which will only happen when the government believes there’s an alternative solution.

Perhaps you could try responding to the point?

Things like Room 641A show that the government doesn't even need to engage the courts to collect data on millions of people and further, that they are not limiting their collection efforts to a few hundreds or thousands of devices a year.

This is patently untrue. Snowden and much more have made it absolutely, unambiguously clear that national spy agencies do wish to gather and collect absolutely and every bit of information possible about their own law-abiding citizens as well as those here that are not.

The ones courts which governed the relevant company were willing to issue warrants on behalf of — that is, those our regular legal and political systems decide on.

For a big multinational like Apple, that’s probably a fair number. But it’s also harder to hide they’re doing that, and let’s us bring pressure on them politically for their political misdeeds. In the end, it’ll be major powers who can — US, Europe, China, etc.

My point is that it’s never going to be the case that technologists get to unilaterally decide that for all of society.

My proposal is just to bring phones into line with existing warrants: https://news.ycombinator.com/item?id=19036408

But by doing so, technologists have the political cover to push back on spy agency excesses and abuses.

So you support China being able to hack any phone globally with a warrant in a Chinese court? Isn't that literally what Huawei are accused of facilitating?
Re:'Karma': A hack used by the UAE to break into iPhones of ... by FakeComments on Wednesday January 30, 2019 @12:00PM (#19036848)
No, I support China being able to spend an appreciable amount of time to crack each phone they have physical possession of, following a court order. I never suggested the ability for remote compromise (what Huawei is accused of), and my exact point is that we can create a cost to cracking each phone — in hashing power and time spent — if we compromise on the topic. No such cost exists now, because they achieve access via other means.

The combination of requiring physical possession and appreciable hashing time per crack is a two-layered response to mass-surveillance. That’s the whole basis of the compromise I’m proposing: calling their bluff, and enabling warrant cracks as political cover to shut down mass surveillance and cracking as unnecessary.

Re:'Karma': A hack used by the UAE to break into iPhones of ... by pjc50 on Wednesday January 30, 2019 @12:09PM (#19036955)
The "hashing time per crack" reminds me of the old 48-bit encryption which was mandated to have short, crackable keys. Or even the previous attempt at doing this with the "LEAF". Are you proposing some sort of work function within the crypto enclave? ie you leave the device brute-forcing for a few days and it spits out the key?

The "appreciable time" is going to be subject to constant downward pressure, both politically and technologically.

> political cover to shut down mass surveillance and compromise as unnecessary

Mass surveillance is not going to go away without huge cultural reform of the security services. They don't take concessions.

Re:'Karma': A hack used by the UAE to break into iPhones of ... by FakeComments on Wednesday January 30, 2019 @05:34PM (#19040322)
I was purposing each phone be loaded with a unique “export key” while being built. For about 1 dollar of GPU time, you can force an attacker to take a month of continuous hashing, on similarly performing hardware. (Okay, people with fancy ASICS could get that down to a week... but that still seems like a big win.)

More details here: https://news.ycombinator.com/item?id=19040252

I agree that it would be a consistent political battle — but it’s already that, and it’s clear people with power are getting fed up with technologists attempting to impose their ideology without compromising with other social needs.

That’s what prompts laws about wiretapping or mandated backdoors.

I haven’t heard the same arguments about safes I do about encryption — and the reason is because there’s an understood bypass, if they gain access, have time and money.

By compromising and allowing targeted cracking, we split the faction pushing for backdoored phones, solve most of the issues, and give ourselves a viable path to accomplish something rather than being forced into backing down or completely compromising systems. Further, by being willing to compromise, we gain a voice on shaping how that discussion looks — rather than largely being excluded.

It's not going to happen on "slightly preferable terms". Either those with political power in society want surveillance, or they don't. If they do, they'll take all that they can get, and the only thing cooperating with them will do is make it all happen faster - the moment you provide a "compromise" surveillance scheme to them on a silver platter is the moment when they'll start devising how to get around the remaining limits.

Total victory, no. Total victory would be strong encryption free to use by everybody without fear of persecution. That looks increasingly unlikely.

However, I do not believe they can effectively enforce any encryption bans. Thus, people who need encryption will still have access to it. And as far as I am concerned, my duty (as a software engineer) is to ensure that it remains the case, even if using it becomes illegal.

Re:'Karma': A hack used by the UAE to break into iPhones of ... by 794CD01 on Friday February 01, 2019 @11:06AM (#19055245)
That attitude sounds like a myopic focus on the software at the expense of everything else.

Say that in the year 2160 you have perfect, unbreakable encryption on your pocket computer. How will you use it? With a touchscreen or keyboard, allowing microscopic cameras to see you input it or read the thermal signatures off your input device afterwards? With your face or voice that are continuously being recorded from hundreds if not thousands of angles? Plugging in the future equivalent of a yubikey that someone can just steal from you? You're lucky if fMRIs don't become good enough to just pluck the information out of your brain as you think it. Of course, the master key is most important but all of these concerns apply to the data being protected as well.

The real thing that can never be effectively enforced is privacy. People who need encryption can have access to it or not. It matters not one whit. Our duty (as people) is to push society in a direction where this change feels less catastrophic, not to fight a Caligulan war against the sea.

You're basically describing a totalitarian Panopticon. A society like that should be fought by all means available, including physical force, so the question of legality of encryption is somewhat moot at that point.

This is not at all how encryption or security works

Re:'Karma': A hack used by the UAE to break into iPhones of ... by FakeComments on Wednesday January 30, 2019 @05:26PM (#19040252)
It’s exactly how it works:

You create a hash chain, then use the final result as an encryption key of your secret (in this case, the key for the data), then store only the start of the chain and encrypted secret.

The only way to retrieve the secret is to recompute all the hashes, from the start, to recreate the key and decrypt the data.

So it’s secure unless you believe there’s a weakness in the underlying encryption or hash function.

Further, you can parallelize this via encrypting the start of chains with other chains — giving a significant advantage to the chain creator: they can do 1000 chains in parallel, but unlocking requires decrypting them sequentially. At that ratio, if you want decryption to take a month of steady hashing, you need only do a little under 1 hour of hashing yourself. 1 hour of 1 GPU is about a dollar of expense, and has more than 1000 parallel tracks.

My suggestion would be that Apple create a chain for each phone and then load it with that phone specific wrapping key — which it uses to return the actual encryption key wrapped in. The only way to decrypt that key is get the necessary information from Apple and a signed request so the SE will emit the encrypted key at all.

Yeah uhh hey I appreciate your enthusiasm but this literally is not how modern public key encryption works, or will ever be changed to work. All ciphers in general use don't have any sort of a realistic time-bound to being cracked or computed
Re:'Karma': A hack used by the UAE to break into iPhones of ... by FakeComments on Wednesday January 30, 2019 @11:25PM (#19042316)
Yeah.

I appreciate you trying to correct me, but I never was saying that this was an instance of “public key encryption”, whichever version you mean.

This is a scheme by which you can intentionally create a key that can be re-generated in a fixed amount of time, and use it as part of normal symmetric encryption to protect a secret. One usage of that is creating intentionally crackable schemes, such as protecting other signing keys in a way you can later crack if you need to. This allows a device, such as a phone, to emit a masked secret that we have cryptographic guarantees it still takes time to recover.

Hashchains for time locking is a studied mechanism, and though it predates crypto currencies, it’s deployed as a mechanism in several kinds of applications there. A second usage is in storing paper copies of master signing keys in a safe, since the key cannot be exposed in the event of a robbery before a certain period of time — giving you time to rekey your system. (Generally, people use multipart keys instead, because they’re less cumbersome to recover; however, if you only have one secure location — multipart keys don’t help. Hash chains still do.)

So it’s literally how (part of) modern cryptography works.

Better yet, scrap the network of cameras and employ a load of uniformed, unarmed police officers wearing body cams. (The cameras should default to deleting footage after a few hours, unless the officer presses a button to save it, and all arrests not recorded due to "missing" footage are deemed invalid).

This helps communities to feel the reassurance of a trusted police presence, creates local jobs, and provides a decentralised alternative to having a single network controlled by a few hidden, unaccountable individuals. Putting a human conscience behind every single camera seems like a good way to prevent tyranny and encourage whistle-blowers.

Yep, just shoulder surf the passcode the user enters on the train, or read their fingerprints/retinal patterns off their body and print it out onto your key material.

If I want to have a private conversation where the details of what are said are undiscoverable, I believe that's a right that people should have in a "free country", including over the internet, over phone, and so on. The fact is, I can, using some combination of math and secrets, accomplish this.

I don't think anyone on earth has the right to collect/record/see the contents of my communications other than me and the other participants, until there's reasonable suspicion of a crime.

Covert dragnet snooping is an evil means to any end, and it damages the moral standing of the society that does it.

The trick here is that the authorities will (somewhat reasonably) advertise their need for these tools under the "reasonable suspicion" label: they want the backdoor or whatever it is they need to conduct their surveillance once they do have reasonable suspicion.

> What’s not going to sell, and what the tech industry needs to get over is “lulz, it’ll impossible to intercept military or terrorist information because I need absolute privacy for my saucy emails”. I think it’s been empirically demonstrated that won’t happen.

It's very much the other way. Strong encryption algorithms have been available to the public for a long time now. You can ban using them, but the only way to effectively enforce that ban would be for the government to require that all devices capable of running code from external sources run only code that's signed by that government.

Without that, you can ban all you want, but terrorists and others who need that stuff will have it anyway. So the only effect would indeed be no privacy for saucy emails. Of course, intelligence agencies would love that, since it would allow them to have a society-wide dragnet.

I disagree with your analysis — the way most people receive encryption, including criminals and terrorists, is through a provider. Regulating their behavior does change the general trend in security. Further, forcing them to implement their own encryption increases the likelihood they make a mistake while also refocusing the NSA et al to those algorithms instead.

What we’ve seen is governments subverting encryption and systems repeatedly, in ways they wouldn’t if they had other methods.

I’m not trying to accomplish some absolute ideological position, I’m trying to shift the state of affairs to realign incentives for several players. If some people write their own encryption, or the technologists use GPG everywhere, whatever.

> allow them to have a society-wide dragnet

I don’t think you even read my proposal: the mechanism I proposed makes that impossible, which is in contrast to the current state of affairs, where they subvert the security of the entire system instead of targeted people. Allowing for targeted cracking at a certain level of expense and requiring physical possession of the device in no way enables mass dragnets, and in fact, removes their legal cover by providing alternative means.

I’m not saying people can’t invent their own security — just that factory made safes need to not be “unbreakable”, because it just incentivized bad behavior when they discover a flaw and/or subverting the integrity of the factory.

You did.

Any attempt at right of privacy must be mercilessly crushed with maximum force

That’s clearly not how the US (or anywhere) operates: the constitution itself negotiates terms between privacy and security — privacy is not and never has been an absolute right.

Further, I’m actually trying to increase privacy, by negotiating a compromise that’s workable for society as a way to remove the excuses bad actors are using, and shift the legal framework around the topic. That’s not an absolute ideological position, by any definition.

By contrast, you do adopt such an absolutist position — which isn’t grounded in law, and fails to provide for other societal needs. Such stances lead to failure, because of their absolutism. Your stance is why Australia passed an internet wiretapping law, not mine — because you refused to acknowledge a societal need until they employed force.

If your approach worked, we wouldn’t have the state of things we do now.

I appreciate the motivation but it's very naive.

Sure, you give them access after 1 month. Next they'll say 1 month is too long, they need to be able to do it within hours to be able to catch criminals before they run to another city. Then it'll be minutes so they can stop crimes while they're happening. Then it'll be real-time on everyone so they can use machine learning to predict crimes minutes before they happen.

They would still have done, and more. You think police and intelligence agencies will one day just say "yeah, that's enough, we're good"? No, they'll want anything that makes their job easier and gives them more power, always.

The objections to a golden key are irrespective of whatever system permits the golden key access. Your hashchains are completely irrelevant. The courts will use some key to sign their request, and that key will leak.

Cryptography reduces message security to key security, nothing more.

Re:'Karma': A hack used by the UAE to break into iPhones of ... by FakeComments on Wednesday January 30, 2019 @05:28PM (#19040278)
That’s why it’s a two stage system: leaking the key only permits forged requests, but an attacker still has to spend the time reversing the hash chain. For each and every phone they want to crack.

Apple has also done a reasonable job of holding onto their signing keys, to date.

How do you know that?

Re:'Karma': A hack used by the UAE to break into iPhones of ... by FakeComments on Wednesday January 30, 2019 @05:54PM (#19040481)
Because whoever has stolen them has been reasonably discreet, and we don’t see compromised Apple things all over the place — which means if they’ve been stolen at all, it’s been by high class attackers.

If your goal is to stop the NSA et al stealing a key or owning a device, you’ll be sad.

But if your goal is to change the law and redefine the parameters of them owning devices, you might make progress. The political process will insist on a means to access these devices, and they’ll accomplish it by one means or another. By engaging with instead of fighting that, we gain the ability to have a say on what those means are.
