Thanks, Jukka, for your suggestion. However, I fail to see how it prevents the I2 storm. The Responder still has to compute three SHA-1s before it is able to check anything. In the current scheme it is enough to compute one SHA-1 before the responder can drop the packet.

However, as we talked later after you send your message, there might be ways to improve the current mechanism in the draft. I'll send a separate message about that.
