Super stealthy Internet messaging method revealed

Princeton University researchers have devised a way to send undetectable messages over fiber-optic networks

A pair of Princeton University researchers presented a paper this week on a method for sending secret messages over existing public fiber-optic networks.

Princeton's Bernard Wu and Evgenii Narimanov made their presentation at the annual Optical Society of America meeting in Rochester, N.Y.

Their encryption technology is hardware-oriented and uses the properties of optical fiber to disguise a message. The technique involves sending a signal so faint that it is hard to detect or unscramble, because it is hidden by the natural optical noise of the network.

More specifically, the technique involves use of commercially available optical CDMA encoders that spread short, intense pulses of light carrying messages. The recipient decodes the message using information about how the message was spread out in the first place, plus compression gear.

Wu said in a statement that he does not believe anyone is using this method yet, because optical CDMA technology is still undergoing much research. He also said there could be a speed tradeoff for increased security.

The paper presented is called "Achieving Secure Stealth Transmission via a Public Fiber-Optical Network."

As with any supersecret network technology, the benefits to companies and government agencies would need to be weighed against the benefits criminals could gain from a way of sending undetectable messages.

Microsoft Office 365/Dell XPS 15 2-in-1

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

It’s useful for office tasks as well as pragmatic labelling of equipment and storage – just don’t get too excited and label everything in sight!

The Brother MFC-L8900CDW is an absolute stand out. I struggle to fault it.

MSI GT75 TITAN

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

If you’re looking to invest in your next work horse laptop for work or home use, you can’t go wrong with the MSI GE63.

MSI GS65 Stealth Thin

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
