Either you are going to have to have a way to disable the missile before you tell it to return, which means that if the manties learn how that is done, they get to turn off your entire attack, or you have to have way to tell the missiles to return to momma without being disarmed, which also allows the manties to foil your attack, and if you aren't expecting it, possibly lead to the destruction of the mothership, and given the stealthy nature of your missiles, makes it difficult to find them afterward, or you have a way of telling the missiles to make themselves known, which can be used to make them visible for destruction during the attack. Anything which allows you to send a signal to modify the behavior of the missiles becomes a way for the manties to use that same signal to foil the attack.
Golly Gee Whiz, lets wring our hands. Oh my, oh dear me, how can we possibly talk to our missiles that is uncrackable for disablement? Uh, duh, one time stamp or several one time stamps that are time sensitive.

You do not need to worry about missiles being "hacked" in the Honorverse unless one ascribes to being able to send a doppler compensated scaled frequency out. Possible, just not probable. After this technical hurdle has been solved, then and only then, can one try to start actually "cracking". Of course we are talking a stealthed drone/missile, so the bad guys have no clue what velocity or acceleration profile to use in order to create the false doppler wave form!
Besides, the RMN FUSION powered drones return to ship and their exploding core would do plenty of damage... RMN hasn't been wringing their hands about their RD's being Hacked when returning to their ship.
