When a system is underattack, do you really want to be using a PRNG for anything like seeding openssl? Because a PRNG is what urandom degrades into when its attacked.
Using a PRNG is not a problem. Making sure it is well seeded and no input from the attacker can compromise its state are the difficult parts. Making predictable estimates and blocking when your estimates are off, makes it a good target for DoS. When your system is under attack, you want to use your services. If they block then the attack might have just been successful. regards, Nikos -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
