Securing peer to peer communications, I mean securing them in any way that would make the effort worth it, is hard. How do you ensure that all the equipment will work together? How do you share keys? How do you keep the compromise of a key from compromising the entire network? The article said the radios were chinese, so how do you do all of that without running afoul of ITAR export regulations and EAR? How do you do this without ballooning the cost of a radio that was supposed to be $30? How do you do this in a way that can be deployed quickly, when the owner wants to go into the field? How do you do this in such a way that requires no coordination between all those that would communicate, but none of those that you don't want to be able to communicate?
The answer, more often than not, is that there is no viable solution. Apparently there often isn't, for things like RQ-4 missions, where imagery is unencrypted.
If you're something like a GMR radio, you can plan for encryption as part of mission planning. If you're just a guy with a gun and an ideology, you probably can't. Doesn't mean you're stupid.
