Editorial: Use of | instead of , for concatenation
Hi again. In section 2.14 of draft-ietf-ipsec-ikev2, it says:
SKEYSEED and its derivatives
are computed as follows:
SKEYSEED = prf(Ni | Nr, g^ir)
{SK_d, SK_ai, SK_ar, SK_ei, SK_er}
= prf+ (SKEYSEED, Ni | Nr | SPIi | SPIr )
(indicating that the quantities SK_d, SK_ai, SK_ar, SK_ei, and SK_er
are taken in order from the generated bits of the prf+).
The parenthetical statement after the equations show that the list
"{SK_d, SK_ai, SK_ar, SK_ei, SK_er}" is really concatenated. That
list should instead be shown as "{SK_d | SK_ai | SK_ar | SK_ei |
SK_er}" to make it clearer that this is not a bunch of arguments but
a stream of octets.
