A growing number of use cases for constrained network - but not limited to - have shown interest in reducing ESP (resp. IKEv2) overhead by compressing ESP (resp IKEv2) fields. The WG will define extensions of ESP and IKEv2 to enable ESP header compression. draft-mglt-ipsecme-diet-esp and draft-mglt-ipsecme-ikev2-diet-esp-extension are expected to be good starting points for ESP compression. draft-smyslov-ipsecme-ikev2-compression and draft-smyslov-ipsecme-ikev2-compact are good starting point for IKEv2 compression. RFC7427 allows peers to indicate hash algorithms they support, thus eliminating ambiguity in selecting a hash function for digital signature authentication. However, advances in cryptography lead to a situation when some signature algorithms have several signature formats. A prominent example is RSASSA-PKCS#1 and RSASSA-PSS, however it is envisioned that the same situation may repeat in future with other signature algorithms. Currently IKE peers have no explicit way to indicate each other which signature format(s) the support, that leads to ineroperability problems. The WG will investigate the situation and come up with a solution that allows peers to deal with the problem in an interoperable way. RFC7296 defines a generic notification code that is related to a failure to handle an internal address failure. That code does not explicitly allow an initiator to determine why a given address family is not assigned, nor whether it should try using another address family. The Working Group will specify a set of more specific notification codes that will provide sufficient information to the IKEv2 initiator about the encountered failure. draft-boucadair-ipsecme-ipv6-ipv4-codes could be used as a starting point for this item. Some systems support security labels (aka security context) as one of the selectors of the SPD. This label needs to be part of the IKE negotiation for the IPsec SA. non-standard implementations exist for IKEv1 (formerly abusing IPSEC Security Association Attribute 10, now using private space IPSEC Security Association Attribute 32001). The work is to standarize this for IKEv2, in a way that will be backwards compatible with old implementations, meaning it must not require any changes to implementations not supporting this. This charter will expire in December 2019. If the charter is not updated before that time, the WG will be closed and any remaining documents revert back to individual Internet-Drafts.
