So, Armchair Chem is an evil corporation that has access to technology some consider unnaturally ahead of its time (the correct term is anachronistic, but whatever).
One such is the Replica Forces. A battalion of highly-trained and heavily-armed supersoldiers. What makes them really efficient is the fact that they form a hivemind, that converges at a commander, and where information, like enemy position/status, can propagate really fast.
This also gives commanders first-hand knowledge of the battlefield without putting them in danger.
Now, the hivemind can only work, if it can't be used against the replicas. If the hivemind can be tapped and manipulated, then the enemy would have all the replicas' knowledge, including the position of their commander, or worse, they could turn the replicas against their commander. If the connection can be jammed, then replicas would become mere paperweight, thanks to the emergency shutdown protocol than puts replicas into suspended animation when not receiving signals from the commander.
How could this hivemind be made resistant to jamming and tapping at the level of individual connections without hindering the speed at which intel propagates?
