Reference

Note
"Key Exchange Method (KE)" transform type was originally 
named "Diffie-Hellman Group (D-H)" and was referenced by
that name in a number of RFCs published prior
to [RFC9370], which gave it the current title.
Note
All "Additional Key Exchange (ADDKE)" entries use the same
"Transform Type 4 - Key Exchange Method Transform IDs"
registry as the "Key Exchange Method (KE)" entry.
Note
"Sequence Numbers (SN)" transform type was originally named 
"Extended Sequence Numbers (ESN)" and was referenced by 
that name in a number of RFCs published prior to 
[RFC-ietf-ipsecme-ikev2-rename-esn-04], which gave it the 
current title.

Expert(s)
Tero Kivinen, Valery Smyslov
Reference
[RFC7296][RFC6989][RFC9370][RFC9395]
Note
This registry was originally named "Transform Type 4 -
Diffie-Hellman Group Transform IDs" and was referenced
using that name in a number of RFCs published prior to
[RFC9370], which gave it its current title.
Note
This registry is used by the "Key Exchange Method (KE)"
transform type and by all "Additional Key Exchange (ADDKE)"
transform types.
Note
To find out requirement levels for key exchange methods
for IKEv2, see [RFC8247].
Note
The instructions for the designated experts are described
in [RFC9370]. While adding new Key Exchange (KE) methods, 
the following considerations must be applied. A key 
exchange method must take exactly one round trip (one IKEv2  
exchange) and at the end of this exchange, both peers must 
be able to derive the shared secret. In addition, any 
public value that peersexchanged during a key exchange 
method must fit into asingle IKEv2 payload. If these 
restrictions are not metfor a key exchange method, then 
there must be documentationon how this key exchange method 
is used in IKEv2.
