Well, there are a couple of signs: First they claim that "conventional
encryption algorithms" are unsuitable for encryption images and
video. To support their assertion, they refer to papers they
themselves have written. (A brief search couldn't find online copies
of these papers.)
When they get to experiments, which is just timings for the algorithm.
Curiously, they have a table that lists what is probably the name
of the image along with the image size and the encryption times.
Why the name is included is anyone's guess. (Perhaps encryption
images of boats is more expensive than encrypting tulips? If so,
can the algorithm be tweaked to make images of nuclear weapons very
expensive to encrypt? That would be a security feature a lot of
newspaper people would love.)
But the amazing thing is that encrypting one megabyte requires two
seconds! They have got to be joking!
