ISAKMP-OAKLEY v4 draft
Dan, on page 13, :
KEYMAT = K1 | K2 | K3 | ...
where
K1 = prf(SKEYID_d, [ g(qm)^xy | ] SPI | Ni | Nr)
K2 = prf(SKEYID_d, K1 | [ g(qm)^xy | ] SPI | Ni | Nr)
K3 = prf(SKEYID_d, K2 | [ g(qm)^xy | ] SPI | Ni | Nr)
etc.
Should "protocol" be included in deriving K1, K2, ..., i.e.;
KEYMAT = K1 | K2 | K3 | ...
where
K1 = prf(SKEYID_d, [ g(qm)^xy | ] protocol | SPI | Ni | Nr)
K2 = prf(SKEYID_d, K1 | [ g(qm)^xy | ] protocol | SPI | Ni | Nr)
K3 = prf(SKEYID_d, K2 | [ g(qm)^xy | ] protocol | SPI | Ni | Nr)
etc.
