The AES::key command should be pretty cheap, CPU-wise. It only accesses the random number generator, and doesn't actually use any AES code. You seem to only be needing a 50-character random string, so you could do something like:
set new_session_value "[string range [AES::key 256] end-49 end]"
which only makes one call to the RNG and only has one string processing command.
