This draft is a work item of the Multicast Security Working Group of the IETF.
Title : MESP: Multicast Encapsulating Security Payload

Multicast ESP (MESP) is a security protocol for IP multicast data.
MESP extends the IPsec Encapsulating Security Payload (ESP) protocol
for multicast operation and supports source message authentication
for multicast packets. MESP offers three improvements to IPsec ESP
for multicast operation. First, it allows a mix of group-secrecy,
group-authentication, and source-authentication transforms to be
applied to an MESP packet. Second, it extends ESP to authenticate
messages sent by a member of the group using a digital signature or
hybrid MAC and signature transform. And third, MESP identifies a
security association (SA) using the IP address of the source in
addition to the destination address and SPI.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
