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

schwit1 writes: 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."

    When considering whether or not it should be okay for the US government to have backdoor access to any device, one should also consider whether other governments should also have that same access. The answer shouldn't depend upon which government you support.

    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.

      It goes further... their scheme requires that the people holding the parts of the key work together regularly whenever access is needed. This is likely to be thousands of times every year. There's no way to keep a secret that needs to be accessed so often by so many. Enigma was broken due to poor operational security, not poor technology. Venona broke one-time pads due to poor OpSec. An encryption scheme used by all authorities wanting decrypts of cell phones would involve tens of thousands of people and would be impossible to carry out without making egregious operational errors. Add to that the fact that none of those who hold the keys have much to lose when they screw up. War time operatives know their way of life depends on them not screwing up. The local FBI office only cares about decrypting the phone, if they screw up, it doesn't hurt them, but it hurts me.

    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.
