Are you using a decent cipher? Modern ciphers should be good
for far more than this, so if this is a work-around for a weak
cipher, you'd do better to simply start using a better cipher.
Then again, maybe you are just being very cautious...
(which is not necessarily a bad thing)
Ok, to answer your question we probably need more info. How
are you deriving your "rotating" session keys? And what
cryptosystem are you using the keys with?
