Re: Not sure that I get it.
I disagree with the use of that term in relation to scrambling. If I scramble a message to send it to someone then the constituent parts of the message are still in the message. For example
the cat sat on the mat
or
mat on the the sat cat
or
ota mhe nta ttc hsa te
You can still reconstruct the message from the parts using a descrambler.
However if I encrypt the message then the original message is indecipherable even if I have all the parts of the message.

Now you can't reconstitute the message by just reassembling the bits of the message. You need to be able to decrypt the message.
