Building Deception Into Encryption Software

ComaVN Re:This is more of authentication than encryption. (106 comments)

Think of it as ROT-n encryption of random data, where n is the key

If you choose the wrong n, you'll still get blob of random data back, just not the correct one.

Now, the tricky part is in making sure the incorrect keys returns data that's hard to distinguish (meaning it can't be done automatically and/or quickly) from the correct plain text, when the plain text ISN'T random looking, but something like passwords, SSN, credit card numbers.

Buried In the Source: "No Expectation of Privacy"

ComaVN Re: How do we get Congress to sign up? (365 comments)

The money you pay in this kind of insurance is ALWAYS more than the expected cost for an individual (ie. the chance they actually have to pay you times the average cost of a canceled holiday)

That's how insurance companies make money. If it was any different, they'd go broke.

So, the payout is basically your own money, and on average, you'd have more money if you had just saved it.

Buried In the Source: "No Expectation of Privacy"

ComaVN Re: How do we get Congress to sign up? (365 comments)

If one has the ability to back up that risk, (...) it is on average better to not get insurance.

I don't get why this concept is so hard for people to understand.

Like people taking out insurance for canceling a holiday trip. If you have paid up front for your vacation, then pretty much by definition you can afford to lose that money without ill effects worse than "I won't get to go on holiday this time"

I'm not sure about other countries, but in the Netherlands only liability insurance is mandatory for car owners, and those will not pay for any damage to your own car in any case.

There exist people less smart than me that can kill me. Yet I don't go around solving that problem by killing them.

Why would the AI be different?

RIM Agrees To Hand Over Its Encryption Keys To India

ComaVN Re:But this is India we are talking about (164 comments)

That was not my point at all.

JoeMerchant was implying his crypto method was perfectly safe against cryptanalysis because it's a one-time pad. However, in the same post he tells us he's not using a one-time pad at all, but a stream cipher.

ComaVN Re:But this is India we are talking about (164 comments)

You just told all of us your method, and we didn't even need to use a wrench.

One time pads are only unbreakable when they're generated with a true random source. What you described is a stream cipher, and as long as you know the key to initialize the keystream, it can be forced from you.

Of course, if you do have a true one-time pad, the location of your copy of it can be extracted just as easily. I'd say the only way to protect against that is to make sure no-one knows you use crypto at all.

Linode Exploit Caused Theft of Thousands of Bitcoins

ComaVN Re:Newsflash (450 comments)

They're exactly the same as the casino owner: the house always gets its cut.

Not quite. The casino sets the rules of the game, making sure they know EXACTLY what the odds are, thereby turning long-term profit into a statistical certainty. The insurer has to guess the odds, and can actually guess wrong, so there's a lot less certainty. That's why there are reinsurers, who insure the insurers against unexpectedly large payouts.

Ask Slashdot: Which Web Platform Would You Use?

ComaVN Re:ASP.NET and C# (519 comments)

The code should be separate from the HTML, not mixed.

That's why you use a framework, or at least a templating engine like Smarty. There's no reason not to do MVC with PHP other than ignorance or (short term) lazyness.

Does PHP support parameterized inputs?


The later versions of PHP (from 5.2 or so) support pretty much anything you'd expect from a modern scripting language. The only problem is, because most of these features were bolted on later, with backward compatibility an important factor, the syntax is less than ideal. In the same way, the standard library is an insane (but reasonably complete) mess in terms of naming conventions, etc.

If you can look at the first table here without wincing you've been doing PHP for too long :P
