In the field of cryptography, a secretly planted “backdoor” that allows eavesdropping on communications is usually a subject of paranoia and dread. But that doesn’t mean cryptographers don’t appreciate the art of skilled cyphersabotage. Now one group of crypto experts has published an appraisal of different methods of weakening crypto systems, and the lesson is that some backdoors are clearly better than others—in stealth, deniability, and even in protecting the victims’ privacy from spies other than the backdoor’s creator.
In a paper titled “Surreptitiously Weakening Cryptographic Systems,” well-known cryptographer and author Bruce Schneier and researchers from the Universities of Wisconsin and Washington take the spy’s view to the problem of crypto design: What kind of built-in backdoor surveillance works best ?

It's probably simpler than that. You just have to be assertive. Be loud. Always claim that you're right, and if anyone questions you, insist that they're wrong.
Keep insisting that you're the only one who understands the math behind cryptography. If somebody challenges you, claim that their proofs are flawed, even if they aren't.
Anyone who follows the computer security or cryptography fields even for a short time will quickly understand that it's more about personalities and strong-headedness than it is about whose theories are proven correct, and whose math is right.

Your words anger me. You don't know what you're talking about. I'm a security expert, and I'm good enough to crack your lousy "Anonymous" Coward defense. Prepare to be hacked. In fact, you already have been. Never mind that you can't see any evidence of it. I'm that good.

Come on, mods. "Flamebait"? Really? This is yet more evidence that the "Flamebait" mod needs to go. Every single time I see it used, it has been used incorrectly. Please, SN admins, get rid of the "Flamebait" mod! It's doing more harm than good.
Or better yet, leave "Flamebait" around as an option. If anyone actually tries to use it, take away all of their mod points and prevent them from ever modding again.

Come on ACs. Complaining about modding? Really? This is more evidence that you need to log in!
Instead of complaining about moderation, you could, you know, moderate.
You could spend your mod points solely on incorrect Flamebait mods if you liked; I imagine you'll prefer to keep whining about it anonymously...
I knew there was a good reason I normally read at +1..

Maybe you'd like to think so but no: no matter the personalities involved, maths simply doesn't work on assertiveness.
Simply because is just a pure intellectual construct (as such, not a science, as it lacks the experimental validation requirements), it does not allow any room for casting doubts - either you demonstrate or you are nowhere no matter how big is your mouth [wikipedia.org].
(no better area where "You can't fool everyone all the time" applies)

The interpretation of mathematics by humans is in fact highly affected by the personalities involved. It's this interpretation that matters the most in practice.

The scientific method makes no requirements about the physical representation of the subject being studied.

I could come up with a pretentious name like "Layer 8 Rollback Attack" and obscure my writing by peppering it with "L8RA", but that would just be an entertainingly meta example of the problem.
If you want to keep people from using crypto, make it hard to use, and most of them will give up and send plaintext.
Some conspiracy-minded people argue that this has already happened due to intentional sabotage. I'm not convinced, but it's alarming that there have been regular spectacular usability problems in mainstream products. It's also disturbing that nothing improves even after usability studies are published.

It is not just cryptography that this method works. I have seen it used to good effect in many other fields.
I usually *let* the other person think they 'won' by backing down. Then just dumping defect after defect after defect on them. Until they relent that they FUCKED THE HELL UP.
"oh ok your right that code is good and working correctly I was mistaken" two days later "here are 50 defects where your code is not working correctly when will you correct it?"
I always give you a chance to fix it up front. Always. But if you are going to play passive aggressive "I am right and you are wrong" in meetings; I will just bury you in process and make you irrelevant because you will be spending all your time fixing something.
