Even with the mil spec transmissions (which by my understanding have un-broken encryption) you could theoretically somehow block 100% data to a receiver, and forward data with timings you want. So long as you are controlling all of the information you don't need to truly understand the cypher text, you are just interfering with the latency. However this is based on what I can remember from 12 years ago, before I'd had any formal electronics/signals education so I might have some massive miss-conceptions.
