Well, not really. That is the most simple way of doing it. But there are
several other ways that are better. One possible idea is to use part of
the nonce as a signature of the rest of the nonce. And part of the nonce
can be a time stamp. This way the impact of replay attacks and DoS
attacks can be minimized. Anyhow, you can do it a lot more complicated
than random :)
