Multicast Extensions to the Security Architecture for the Internet Protocol

The Security Architecture for the Internet Protocol [RFC4301] describes security services for traffic at the IP layer. That architecture primarily defines services for Internet Protocol (IP) unicast packets. It also defines services for manually keyed Security Associations (SAs) matching IP multicast traffic selectors. This document further defines the security services for manually and dynamically keyed SAs matching IP multicast traffic selectors within that Security Architecture.
