I happen to like guns and shooting. It's a good point to understand the appeal of guns and also "the other side."

But there is a point you are leaving out that comes up if you talk to anyone who does treat firearms seriously: many people do not take those classes and/or do not treat guns safely. Go to a range on Sunday and that will be really clear. Or read the comment history by people who bring this up whenever guns come up in a general forum. Often they rightly end up complaining about safety of other gun owners in posts in more topic specific forums. But somehow, when it comes to a general audience, those issues get omitted.

Taking the class would give you a distinctly wrong impression about the responsibility of all gun owners. As does the suggestion to take the class.

Sorry, not to single you out specifically, it really is a good suggestion. But the net rhetorical effect of people making points like this is (and I think it's intentional) to skew the framing of the issue. Yes, you may be responsible, but with the exception of some people who would never heed your advice, people who want more regulation of firearms aren't worried about you. Guns don't kill people, some people with guns kill people.

Instead of using the NIST recommended curve points it uses self-generated basis points and then takes the output as an input to FIPS/ANSI X.9.31 PRNG, which is the random number generator used in ScreenOS cryptographic operations."

Looks like they feed the output through a standard CPRNG. Assuming it's true, that pretty much breaks the DUAL_EC attack because you can't use the output of the final CPRNG to recover the DUAL_EC state.

The usual distance bounding protocols only need a nano-second accurate timer on one device called the verifier. For example https://www.usenix.org/legacy/event/sec10/tech/full_papers/R...

Cool trick in that one, the Prover(i.e. the key fob) does the distance measuring part of the challenge response protocol using analog only components. This means its response time is <1 nano second.

So you can do it with only the car having a good timer.

It might be true, but how usefulness is it when dealing with society as a whole?. For the Puttman, it probably kicks in, but for a whole field like e.g. programing/computer science/IT, it almost certainly doesn't for the simple reason that the field isn't composed of anywhere near the top 0.001 percent of the population in terms of IQ.

Summers's point was about the distribution at the extremes, not the average. He was addressing the lack of professors in STEM at places like Harvard which manifestly select for the far end of the bell curve. Right, wrong, or otherwise, that has almost nothing to do with the average case and even he contended that the best statistical evidence showed women and men were roughly equal.

So, unless one seriously thinks that the entire field of programming/IT/computer science as a whole requires that level of talent, Summer's point doesn't apply and there are certainly other reasons for the gender gap in computer science.

Sure.

Lets suppose it actually was a valid defense. But what does that have to do with going through the Facebook and personal email of individual employees to know who to target. That was done up close, in personal, by hand. By any definition, those people had their privacy specifically and intentionally violated by actual human analysts.

So I may have missed the details. I thought we knew they hacked Belgacom, but no one mentioned going through employee's personal email and social networks (though in light of this, we can assume they did). If they did mention it and I missed it, sure, nothing new. But the same entire thing then just applies to that instance too.

Because they were useful for targeted surveillance? Not that I agree with the means or the scope, but there's an above board explanation for the desire to get the keys . Suppose you have a handful of phones in Pakistan or Iran you need access to very covertly (e.g. some rogue guy in the ISI where getting caught snooping has major consequences). The least risky way to access his communications is to get the keys. The least risky way to do that is to get them from the broadest source possible(to obscure who you're really interest in) and the one most removed from your target. So there's a legit reason to want the keys, even if your only targeting a few legit targets.

But the means of doing so is truly questionable, even given all their assertions about trust us and we don't look at everyones stuff.

The SIM card bit is actually I think a distraction. The real issue should be the means: the NSA/GCHQ intentionally targeted innocent/non government affiliated people's personal email and social networking.

That's different than collecting everyone'ss data and claiming you never look at it unless someone does something to loose their innocence. Orwellian nightmare that that is and probably bullshit, revelations along those lines are not surprising. The systematic targeting of the personal lives of random employees (at least of non-governmental/ non defense industry ones), is new.

Personally, the biggest take away to this is the invasive targeting of completely innocent and ordinary people simply as a means to get access to things the NSA needed (sim Card keys). We have concrete evidence they nailed peoples personal email accounts and social networks merely as a means to an get crypto keys in mass. Sure, the potential mass surveillance is exceedingly problematic, but thats mainly problematic because of the potential for abuse. Abuse that we either assumed would happen or already had, but as far as I know there was little direct evidence of.

The absolute lowest bar for surveillance seems to be that a government doesn't use it to intentionally target innocent people/ those not in the game (hell, lets lower it even further to be only people the government themselves believe are innocent).[0]

That potentially allows dragnet collection of data if no one looks at it. It might allow hacking just a company's servers to get access to third party data. It probably allows you to spy on foreign heads of state (even if it's a boneheaded move). But it damn well doesn't allow you to go through the personal communications of people who you know have done nothing wrong and aren't even working for someone who has.

[0] This is precisely the woefully low bar Obama has been espousing : “The bottom line is that people around the world, regardless of their nationality, should know that the United States is not spying on ordinary people who don’t threaten our national security and that we take their privacy concerns into account in our policies and procedures,”

The notation that a debate on the rules of digital warfare will do anything is questionable.

Arms control limitations (SALT,START), the hague convention, etc, work because there are means of verifying countries adhere to what they agree on (and ostensibly punishing those who don't).

Given the difficulty of attributing cyber attacks (e.g. Sony), much less cyber espionage, there's little reason to think this is possible in this case. And that's just for direct action.

If we're talking about tactics and capabilities, it's impossible. How are you going to make sure there aren't 30 people somewhere writing malware for a government? You can't, at least absent far more invasive spying or some kind of DRM that makes writing malware illegal.

Not this paper again. It can't be used for cryptographic usage and the title(which is the original title of the paper) is completely misleeading.

The device you're authenticating must have the secret you're authenticating with in it in a retrievable format. So it can't be used for e.g. disk encryption, etc, because the attacker can just get the secret from the device and decrypt.

All it can be used for is authentication, and for that they require a human security guard to ensure it's actually a human playing the authentication game. If you were to attach a computer, its likely it could impersonate you. So almost completely useless (except for getting people's hopes up).

People being more social doesn't necessarily mean it was because the women were more social. It could simply be people were more social because it was a more diverse environment ( I at least can get bored of talking to the same people all the time or even the same type of people).

There aren't. Nacl certainly is credible. But it isn't (at least last time I looked) portable. As I understand this is because of a bunch of x86 assembly meant to generate very fast and constant time crypto code.

This is Bernstein's entire stick. Which is fine, but if you can't use it on ARM and therefor on mobile, you've killed a large area where adoption of new crypto could actually happen. Arguably, a slower constant time cross platform library would have been a better idea if he actually wanted to see it used widely. This is what Sodium claims to be ....but well who knows if that's secure.

And I don't think I agree with you that this is Bernstein merely saying here's why you need what I've done. It's an explanation of why it didn't happen that basically argues that people' are being so stupid about crypto that they might as well be NSA shills. As a narrative it ignores a lot of reasons this stuff didn't happen and a lot of lessons that should be applied in getting it right this time.

It's a terrible piece of self reflection in that case. His thesis is his stuff never got adopted because of the NSA? DJB is very smart, but he doesn't necessarily play well with others (as tptacek alluded to) and sometimes does some odd things.

As a random example: Nacl, which is pretty good, isn't portable. The portable version that someone made, Sodium ripped out a bunch of the platform specific stuff to make it portable, but because no one knows which parts were security critical and which weren't,there more than some doubts. These kind of things matter.

Put another way, as a piece of self reflection at least he could figure out how to make it harder for the NSA to marginalize his ideas if that's really the reason they haven't been adopted.

The article quotes the judge as saying"

    "Defendant could have established such a personal privacy
     interest  by submitting a sworn statement that could not
     be offered against him  at trial as evidence of his guilt 
     (though it could be used to impeach him should he take the 
     witness stand)"
So it's not as Kafkaesc as the title makes it sound---he could have said it's his without incriminating himself---but it's still pretty kafkaesc in that it would have effectively prevented him from testifying.

Remote controlled drones have limitations due to electronic warfare/jamming (not to mention security, see the one the US lost in Iran). There's also an issue with lag.

Actually autonomous ones are as far as I know only good for static targets (effectively they are reusable cruise missiles).Close air support or deciding whether to engage an enemy airplane or not gets tricky.

No, no it doesn't. It's a perfectly valid answer (given appropriate evidence). The point is it's an answer to rebut data and it's one that it self requires data. In no way does it stand as an argument that we should not have the data in the first place.

Again, the presumption about a a post-racial society requires evidence. That evidence may be that ethnic identity issues explain discrepancies, but it can't be an argument because we live in a post racial society , data to the contrary should be ignored.

Because if there are large systemic racial inequalities (not that I think employment at Google is worthy of the title, compared to things like education and incarceration rates), then we manifestly aren't in a post racial society.

Given the history of legal and social discrimination in the US, the impetus is on the people claiming we live in a post-racial society to back that fact up.

Depends entirely on why and how it was encrypted. If we are talking about the flight control software, the airplane must(edit,not necessarily) have the keys to boot clearly.

If we are talking about recorded data, it's less clear. The imagery data may be encrypted to provide access control after the drives are removed from the plane and handed somewhere else. In which case, there's little reason the drone wouldn't have the decrypt keys.

You could encrypt the data with a public key and store it so that the drone itself can't read it. About the only reason to do this would be to ensure if it was captured, the target wouldn't see what was on it. I'd suspect the way the military planed to handle that eventuality, however, would use on an exothermic random number generator (a.k.a. a self destruct mechanism/ explosive charge) rather than encryption. There's a lot of way more sensitive thing on the aircraft than just what it took pictures of that you need to destroy.
