XMPP WG Delta Between IETF 55 and IETF 56

This document summarizes the changes made to the XMPP Internet-Drafts between IETF 55 (Atlanta) and IETF 56 (San Francisco).

XMPP Core

The following changes were made to draft-ietf-xmpp-core:

XMPP IM

The following changes were made to draft-ietf-xmpp-im:

Nodeprep

The WG published a new document, draft-ietf-xmpp-nodeprep, defining a stringprep profile for node identifiers in XMPP. It was desirable to publish a standalone I-D for this profile to ease registration of the profile.

Resourceprep

The WG published a new document, draft-ietf-xmpp-resourceprep, defining a stringprep profile for resource identifiers in XMPP. It was desirable to publish a standalone I-D for this profile to ease registration of the profile.

End-to-End Encryption

The WG published a new document, draft-ietf-xmpp-e2e, defining a basic mechanism for end-to-end encryption of message-related information. This I-D superseded the earlier appendix to draft-ietf-xmpp-core and addresses several security requirements in RFC2779. In particular, it improves upon the earlier appendix by encrypting the complete message stanza (not just the message body) and by including a unique id value to help prevent replay attacks.
