> view it from NIST's (/ NSA's) perspective for the sake of argument. Maybe there's a specific threat where NIST (or presumably the NSA) believes it has a mandate to insert a backdoor.

Without any /sarcasm tags I have to take that on face value, and frankly there are few words to fully describe what a colossally stupid idea (not your idea, I am sure) that is. Belief in containable backdoors is the height of naivety and recklessly playing fast and loose with everyone's personal security, our entire economy and national security.

That is to say, even taking Hollywood Terror Plots into consideration [0], I don't believe there is ever a "mandate to insert a backdoor".

> In order to successfully do this, NIST needs to maintain a very large bank of social capital and industry trust that it can spend on very narrow issues.

Having some "trust to burn" is great for lone operatives, undercover mercs, double agents and crooks that John le Carre described as fugitives living by the seat of expedient alliances and fast goodbyes. Fine if you can disappear tomorrow, reinvent yourself and pop up somewhere else anew.

But absolutely no use for institutions holding on to any hope for permanence and the power that brings.

> The inevitable outcome is that NIST loses much of its influence on the industry, which certainly is not in its own interest.

Exactly this. And corrosion of institutional trust is a massive loss. Not for NIST or a bunch of corrupt academics who'd stop getting brown envelopes to stuff their pockets, but for the entire world.

But since you obliquely raise an interesting question... what is NIST's "interest" here?

Surely we're not saying that by spending trust "on very narrow issues" it's ultimate ploy is to deceive, defect and double-cross everything the public believe it was created to protect? [1]

I'm all for the game, subterfuge and craft, but sometimes you just bump up against the brute reality of principles and this is one of those cases. Backdoors always cost you more than you ever thought you'd save, and I've always assumed the people at a place like NIST are smart enough to know that.

What if it is acceptable for potential enemies to (eventually) also have access to that backdoor, and your goal in providing the backdoor is just to give the masses a false belief that they can communicate secretly?

Obviously those in the know would not use the flawed system, but instead would have a similar/better one without the intentional flaws.

> Obviously those in the know would not use the flawed system

Perhaps the clearest argument against such a ploy is the TETRA radio system. Turns out in this case that "the masses" are our:

- police and emergency services

- military and civil defence forces

- diplomatic and political security, escorts, attaches and close security

You see the problem is this concept of "in the know". It's an insoluble information-hazard and boundary problem;

Two people can keep a secret, if one of them is dead.
