Section 8 says:
Sections 8.1, 8.2 and 8.3 say "We suppose that the response Diffie-Hellman private key is:"
It should say:
"We suppose that the responder's Diffie-Hellman private key is:"
While the text did not cause me any problems in testing my P-256 implementation, it did initially confuse me. IKE has initiator and responder. The way the text is currently phrased, it seems as if the private key is sent in response to a message from the initiator.
