The Multicast Security (msec) working group in the Security Area has concluded. The IESG contact persons are Sean Turner and Stephen Farrell. The msec working group has completed its primary charter items, and is officially closing. The mailing list and list archive will be retained. The msec working group was primarily focused on standardizing protocols for securing group communication over Internets, and in particular over the global Internet. Some of the working group products include: The Multicast Group Security Architecture (RFC 3740), The Multicast Security (MSEC) Group Key Management Architecture (RFC 4046), MIKEY: Multimedia Internet KEYing (RFC 3830), GSAKMP: Group Secure Association Key Management Protocol (RFC 4535), Multicast Extensions to the Security Architecture for the Internet Protocol (RFC 5374), and The Group Domain of Interpretation (RFC 6407). We would like to thank all of the IETF participants who have contributed to the various documents produced by the msec working group and to the successful completion of their deliverables. We especially thank the working group's co-chairs: Ran Canetti, Lakshminath Dondeti, Brian Weis, and Vincent Roca. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
