Quantum 'Unbreakable' Encryption [news.bbc.co.uk] Unveiled
Perfect secrecy has come a step closer with the launch of the world's first computer network protected by unbreakable quantum encryption at a scientific conference in Vienna.

The network connects six locations across Vienna and in the nearby town of St Poelten, using 200 km of standard commercial fibre optic cables.

Quantum cryptography is completely different from the kinds of security schemes used on computer networks today.

These are typically based on complex mathematical procedures which are extremely hard for outsiders to crack, but not impossible given sufficient computing resources or time.

But quantum systems use the laws of quantum theory, which have been shown to be inherently unbreakable.

It looks like an entire hardware network is required to implement this system. I guess we'll have to wait until everyone is connected end-to-end with fiber optics to get such encryption on an Internet scale.

Better still use womens logic, no man has ever been a able to crack that one. (sorry to the women on the forum, ill say it now)

Unbreakable eh? Sounds a lot like "unlimited bandwidth".

lol @ Essex_boy

'Inherently Unbreakable' sounds like 'requires a huge initial spending on infrastructure and software which will only work with the most up-to-date hardware because the math requires uninterupted access to super-computers in order to decrypt the continually mutating algorithms which model quantum mechanics' (see also "Not for the masses" or "convoluted system which is 'inherently problem laden'"). Then again, I didn't bother to read the full article...

Essex_boy- very difficult (if not impossible) to crack, yet very easy to bypass. A dozen roses often gets in the backdoor and bypasses the logic.

Haha.

If Divide by Zero (No Logic Present)
Then Password Reset (Roses - FTW)

Am I reading that right? Either way, I have tossed my hat in with the two of you and offended all XX chromosomes...

LOL - Just a simple sly thought to melt an iceberg in a moment. All things are possible, the impossible commonplace:))
