Story: Researchers claim stealth encryption breakthrough

Old news and not accurate ... This type of trick people have been trying since World War II with normal radio waves. Since you can easily detect, with the right equipment, the higher energy densities of parts of the spectrum that contain the extra information it will not work. Only if you use ridiculoulsy low data data densities in the stream will you be able to truly stay unnoticed from a statistical c.q. mathematical point of view. The data throughput bandwidth will however become almost unusable.

Anyone with a decent background in signal analysis can see this. It is based on an old idea regarding simple spread spectrum techniques with data "hidden" in the noise. Using Fourier Analysis you can however detect the higher energy levels. Detecting which peaks are part of the datastream is another thing offcourse. So Stealth it is not.

Is it encryption?

No. It is security through obscurity. The security is based on the fact that you would need the key to know at which frequencies to listen at what time and for how long.

Can this be cracked?

If you have the money to listen to all frequencies simultaneously using a sampling rate that is faster than the minimum length of a signal that transmits 1 bit. So yes in theory you can crack such a system.
