Done properly, especially with one time pad encryption,
one can handle this sort of situation.

Consider... the use of CD-R's for pads. They give you 650
megabytes of storage. Assume one message of 1k contents
per minute is sent; that works out to a bit over 43 megabytes
of pad per month, or about 518 megabytes per year. Each receiving
station can have its own pad and its own recipient keying.

The messages are sent, every minute, every hour, every day.
Most of the time they decrypt to "Nothing is happening,
the wind is west at ten kilometers per hour in central
Bagwabadad, the temperature is twenty three celsius,
our fearless leader

(It's generally not a good idea to use canned phrases like this)

wishes you good will guarding our
important sacred borders, have a nice day. [spaces padding
out to 1k total chars]"

Or better still, make the null messages just encrypted nonsense.
