U.S. Gov't Grapples With Clash Between Privacy, Security

WaPo: "For months, federal law enforcement agencies and industry have been deadlocked on a highly contentious issue: Should tech companies be obliged to guarantee U.S. government access to encrypted data on smartphones and other digital devices, and is that even possible without compromising the security of law-abiding customers?"
NSA director Adm. Michael S. Rogers wants to require technology companies to create a digital key that could open any smartphone or other locked device to obtain text messages or photos, but divide the key into pieces so that no one person or agency alone could decide to use it. But progress is nonexistent:
"The odds of passing a new law appear slim, given a divided Congress and the increased attention to privacy in the aftermath of leaks by former NSA contractor Edward Snowden. There are bills pending to ban government back doors into communications devices. So far, there is no legislation proposed by the government or lawmakers to require Internet and tech firms to make their services and devices wiretap-ready."

An example of how to do cryptographically secure secret sharing:
Shamir's secret sharing.
There are other secret sharing schemes there, follow the link to the main article.
One should also remember that government employees with privileged access are people, and people can misuse the access they have.
We should recognize that the Fourth Amendment of the US Constitution was created to prevent this exact scenario. Law abiding people encrypt sensitive information to protect it from misuse by criminals, but the information can be misused by ANYONE with access.
Dividing a backdoor key between multiple parties simply creates a requirement that all parties agree to access the information before it can be accessed. It doesn't guarantee that the access will be lawful.
So... what makes the NSA think that anyone could actually keep these ultimate "keys to the kingdom" secret? I mean, just about everything else of theirs that was secret has leaked out thanks to a single contractor. Can you imagine how valuable these keys are, and how much money could be made by selling them? Hell, the US couldn't even keep our nuclear weapon plans under wraps.
And what's awesome about this scheme is that once the secret is out, every single smartphone in the US is compromised all at once. Whee!
Irony: Agile development has too much intertia to be abandoned now.
No matter how many US agencies you distribute the key over, one thing is absolute certain: If you require US companies to make any and all contents on mobile devices available to US government (and, considering who owns it, US corporations), absolutely NO non-US company could sensibly buy anything anymore from a US tech company.
Hell, the chance to not be spied on would be bigger if you bought Chinese crap!
Quite seriously, why should anyone trust a country that has a worse record when it comes to industrial spying than China?
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
They can have a back door to my phone - as soon as they give me the key to all THEIR systems (up to and including the President and IRS etc) so that when WE have the right to data, they can't say "we lost it". What? Its only fair - they watch me, I watch them

There's no clash. The law is perfectly clear on that subject. Only the government is choosing to ignore it.
Seven puppies were harmed during the making of this post.
Dr. Petrov: [Ramius has taken the Political officers Missile key and kept it] Sir! The reason for having two keys is so that no one man may...
Captain Ramius: May what, Doctor?
Dr. Petrov: Arm the missiles Captain.
Captain Ramius: Mmm, thank you for your concern Doctor

There's not supposed to be, but there are. Every time a secret court like FISA makes a secret decision, new secret law is created on the fly. Secret precedent.
And by the way, there's also supposed to be no such thing as anonymous local police in the USA, but they take off their ID and pull balaclavas over their faces at the sight of three black people walking down the street with a protest sign.
There are a lot of things in the USA that are not supposed to exist. Secret laws, secret courts, secret trade agreements. Secret police. Secret police blacksites. Secret "crowd control" weapons for the secret police to use domestically. Torture. Rendition. Off-shore prisons. Extrajudicial assassination.
And secret donors, of course. That's what it's all for. There was a secret coup in the US decades ago, and we were collateral damage.
You are welcome on my lawn.
If a backdoor key exists, then the company that created it must by law give it to any lawful government authority that requests it. For example, if a company does business in Saudi Arabia, and a backdoor key exists, they may be compelled under Saudi law to give that key to the Saudi's. If a company does business in Russia, they may be compelled by the Russian government to give them the key. That's the nature of a backdoor. You can't just give it to only one entity. And let's not forget about Gemalto. They have cellphone encryption keys for the SIM cards they produced, which were held on their servers so that law enforcement agencies could obtain backdoor access to cellular communications via the legal process. However, the NSA broke into their servers and stole all of their secret keys, and then used them to mass decrypt cellular traffic. That's a real example of key escrow in action, and it completely failed to protect anyone.
I wouldn't doubt thaht the NSA has broken iPhone's encryption.
This proposal by NSA mirrors the Clipper Chip/Skipjack + Key Escrow system proposed back in the early 90s. People didn't trust the government with their keys THEN... why the hell should they do so NOW, given that government intrusion into our lives has only increased in the interim?
Unlike the 90s, by now they have proved they can't be trusted.
It is in the interest of anybody to help in providing the best possible encryption because "Whatever govs can do, crooks will do better". It not only helps the industry or privacy. It also protects itself as it is likely that such mandatory back doors will be technically outdated and hacked quickly after put in place. Weak Encryption has decided the fate of Mary Queen, the deciphering of the Zimmerman telegram a hundred ago played a role in the outcome of WWI and weaknesses in the use of the enigma cryptology was important in WW2. Since then, technology has exploded and become more important everywhere. Any government proposing to weaken its own communication infrastructure by mandatory crippling their own industries will be in a disadvantage. The dream is of course that high up, secure systems are going to be used. As they will not have been well tested, they are likely to be hacked even faster than a device for the masses with a backdoor which has withstood standard attacks and gone through peer review by hackers. And if some really sweet military grade encryption will remain to be safe, it will be a goldmine for a company selling devices with such additions abroad.
