Re: eliminate AH -- unanimous
Before the WG eliminates the AH, we must remember that there are other
protocols being developed that rely on the AH option, specifically Mob
ile
IP. Mobile IP control messages (Registration Request, Reg. Reply, BIn
d
Update, Agent Advertisements, etc.) all rely on IP AH to provide
authentication. If AH is dropped then Mobile IP will be forced to
implement its own form of AH mechanism.
Bill's suggestion is not that the functionality of AH be eliminated,
but that it be eliminated syntactically as a header distinct from ESP.
ESP with authentication and null encryption does the same thing, but
with small changes to the definition of what is protected.
