FBI: Magic Lantern has a nemesis READ

[artcarved]

This is in response to the FBI's new encrytption cracker. The following info comes from the current TIME magazine on sale now, dated Nov. 26, 2001. Here are some highlights:

"Richard Hughes, 47, a researcher at the Los Alamos Dept. of Energy in New Mexico, has developed quantum cryptography. Combining cutting-edge encrytpion with the arcane of subatomic physics. Hughes designs coded messages that can neither be broken nor intercepted."

"Here's the problem: codes only work if both parties, sender and receiver, have the key- and at some point they have to pass that key between them in an unencoded form. As a result, all conventional cryptosystems are theoretically vulnerable to eavesdropping."

" Here is the solution: embed the key in a series of single photons in such a way that the laws of quantum mechanics prevent it from being intercepted. It's perfect."

"By sending a series of photons polarized at different angles, Hughes can transmit information: each particle represents a single bit- a 1 or 0, in a computer language."

"The result is an untappable line of communications."

TIME Magazine, Nov. 26, 2001., articly by Lev Grossman.


Unfortunately, this won't be available for a couple years...

BUT I WANT MY FREEDOM!!!!!!!

Wow, that sure sounds interesting

 

[HappyScrappy]

yes - but this doesn't prevent the eavesdropping - it just allows you to know that you are being listened to.
if the photon has shifted its state, then that means that it has been observed along the line.

and this is going to be beyond us for more than a couple of years...

Here's more:

"The result is an unstoppable line of communications. It would be easier for a potential eavesdropper to pick a single snowflake out of a blizzard than to track down a single photon in flight. What's more, like snowflakes, photons are fragile: according to the surreal logic of quantum physics, the very act of observing one alters it irrevocably."

 

[Code]

QC is nowhere near the point where end-users will be able to use it.

QC also is very effective at Breaking Encryption. In fact, I'd say any break-throughs with QC benefit those wishing to hack encryption moreso than help it.

which would be the part to which I was referring to.

the main reason it is hard to tap, is with an electronic connection, you can monitor it with a coil nearby (around or on the wire) - but with optics, you need to divert the signal or split/double it off - it is harder to deal with b/c there isn't any electromagetic issues at hand, let alone leakage to listen to.

but all of this is soley in theory - they haven't done this on any real scale yet.

the single snoflake out of the blizzard isn't quite the right anaolgy since you would just take the blizzard. each photon would represent a bit, so if you grab just a single one, all you know is that spot is a zero or one.

but this is all very cool stuff - just wish it wasn't such extreme vaporware - and the gov'ts will see it long before we ever do as regular consumers... as with most things like this.

heisenburg is still helping us after all these years....

as I understood it - quantum cryptography and quantum computing are two different fields - the computing would allow instantaneous braking of any current code we have (given enough thrown at it) - whereas the crypt is the light beam, which currently has most efforts going towards voice data....

but agreed - both are so far from us seeing it that they are just "gee whiz" sorts of things at this point.

SPARKLE was an attempt at quantum computing towards breaking encryption - but it wasn't truly quantum in nature but instead more of a massively parallel effort of analysis

 

[artcarved]

With all of this terrorist shit, we are fucked. The gov't will get whatever they want. I fucking hate this. I realize both sides, I just want to be left alone. We on the board are all law abiding citizens.

 

[Code]

Basically the RNG for quantum crypto *is* the quantum event itself, ie. photon acceleration, gieger counters etc.

But yes, QC is a seperate issue with the caveat that qcrypto won't be a reality until QC is available.

 

[artcarved]

I admire the knowledge of many of you. Teach me.

Any

crypto is breakable, unless of course you want to take into account Artificail intelligence, for instance i send an encrypted message, the message has the ability to sense if it is or has been intercepted then it could reveal a fake message. I love SCI-FI, and the older I get the more real it becomes.

 

[Code]

Even your theoretical AI crypto has potential flaws. Spoofing the proper recipient is one of them.

But your theory has already been put into use. Entrust used to make modules that does what you outlined if the ciphertext is "opened" with the wrong key pair.

 

[artcarved]

Big dUMP, for those who might be interested. I can't stand losing our privacy.

I downloaded

ZONE ALARM PRO version and guess what.... When you bring up elite fitness it asks my win2k os if it can have server rights!!!!!!!!!!!!!!!!!!!!!

So basically if I said yes this site can hack your system! Server rights allows a connected computer the same access as you have. I said NO and still can post and etc...

FOOD FOR THOUGHT

 

[Code]

I'm assuming you don't know how the web works gethrd.

When you 'view' a site you are logging onto the machine hosting it. Meaning you are a user of that machine's resources.

So it would only seem logical that if a site you log into uses activeX, java or php that it must have some rights to your machine in order to run them locally for you.

So the reverse also applies as well, meaning *you* have certain rights to a site you are viewing.

 

[gethard1]

I do know

how things work and out of 4 other boards of the same type this was the only one to want SERVER RIGHTS there is a difference to server rights and running active X java VB locally on your personal machine.

You do not scan a persons machine when logging on to the site, especially through suspicious ports commonly used by hacking software ie internet periscope brought the port access into the light and if that does happen your supposed security through your browser should alert you to active x and or scripting activity, if and only if you have your system configured as such, and I do.

If you are not monitoring those specific ports for access you would never know because the standard security configuration is not able to do so.

I am not claiming to be an expert, nor am I trying to cause turmoil, I did not start this thread.
