The IESG has received a request from the Multicast Security WG to consider the following document: - 'An additional mode of key distribution in MIKEY: MIKEY-RSA-R' <draft-ietf-msec-mikey-rsa-r-04.txt> as a Proposed Standard The document specifies a new MIKEY mode. The main goal of the new mode is to address the one-to-many use case, where the transmitter does not know in advance the certificates of all receivers. None of the existing MIKEY modes covers this case. In the new mode, the recipient initiates the exchange. In response, a key comes from the transmitter of the protected data. The entire exchange takes one round trip. Replay protection is obtained via timestamps, as in other MIKEY modes. The mode can also support unicast, where the usability is roughly the same as existing DH modes. This new mode allows MIKEY the same flexibility and usability as other multicast key management protocols, enabling a single sender to manage keys for a dynamic large group of recipients. The document was discussed several times in MSEC WG meetings and on the MSEC WG mailing list. The authors have SIP, RTP, and MSEC expertise. Several people provided reviews, and at least two of them were comprehensive. There were no objections to publishing this document as a standards-track RFC. The protocol is specified in sufficient detail to allow independent implementations. There are no known implementations, but implementing MIKEY-RSA-R mode, given a MIKEY-RSA mode implementation is fairly straightforward. The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send any comments to the iesg@ietf.org or ietf@ietf.org mailing lists by 2006-05-19.
