Nothing fundamentally difficult about secure comms these days.
Review the literature, choose an algorithm that has been
in widespread use for a few years without significant vulnerabilitys
beig found and use plenty of key bits.
The problems of things like WEP have arrisen due to system designers
a)ignoring the principles that the cryptographers have spent years
working out
such as keeping the algorithm secret only helps short term and
algorithms
created by people who havn't spent twenty years learning
cryptoanalysis
usually turn out to be insecure.
and b) cuting down the crypto to fit the amount of processing
and battery power available. Technology has moved on to
the point that should not be a problem anymore.
