question on IKE between HA & FA in 3GPP standard...

[Suresh Iyer <siyer@megisto.com>]

Hi,
	I am trying to identify the requirements for IKE between Foreign
Agent & Home Agent.
In the Annex A to the 3GPP2 Wireless IP network standard, 3GPP2 P.S0001-B,
it is specified that
aggressive mode be used with preshared keys and main mode be used with
Certificate authentication.

It also specifies that "Signature payload" will not be sent by PDSN (FA) and
HA.

Does this mean that the certificate authentication is to be done with
"public key encryption" and not "signatures"?
