I did a lot of work in trusted computing in a hostile environment a
few years ago. So long as the person running the code can alter the code
you can not prevent this, period. Of course you can make it more difficult,
but never prevent it. Try compressing the executable with one of the tools
available. Also make sure you strip the executable before sending it out.
Anything more will probably involve OS specific alterations.
