Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
The hardware can be protected if they are kept physically safe and the schematics and assembly procedures are burned after the production run.

There's all kinds of games you can play with the software: data binary word length, binary word placement, algorithm cycling, synch/desynch on the transmissions, burst/stream transmissions, wide band/narrow band, etc. etc. etc.  

I wouldn't trust any generally available encryption programs.  If they are a usual part of the IBM software then they can be cracked if enough resources are thrown at the problem.  

Despite everything, above, One Time Pads are the only way to go if you want to ensure security.

They'd have to steal them, copy them and reinsert them into your logistics before you notice they're gone.

Possible, in theory, but if the other guys can pull that stunt then your organisation is either so hopelessly compromised or crushingly incompetent that somebody stealing your bombs mid-flight is not the greatest of your concerns.

Keeping stuff physically safe is pretty hard in a combat environment. See how the Soviets got hold of the Sidewinder technology...

Meteor Scatter Telemetry is harder to intercept, works even if satcoms get busted, and is way way cheaper.
