 Therefore, this document delegates details on the communication and security approaches used in a group to separate application profiles. These are specialized instances of this document, targeting a particular group communication approach and defining how communications in the group are protected, as well as the specific keying material and configuration parameters provided to group members. In order to ensure consistency and aid the development of such application profiles, this document defines a number of related compliance requirements (see {{req}}).
 
-New keying material is intended to be generated and distributed to the group upon membership changes (rekeying). If the application requires backward security (i.e., new group members must be prevented from accessing communications in the group prior to their joining), then a rekeying has to occur every time new members join the group. If the application requires forward security (i.e., former group members must be prevented from accessing communications in the group after their leaving), a rekeying has to occur every time current members leave the group or are evicted from the group.

 A group rekeying scheme performs the actual distribution of the new keying material, by rekeying the current group members when a new Client joins the group, and the remaining group members when a Client leaves the group. This can rely on different approaches, including efficient group rekeying schemes such as {{RFC2093}}, {{RFC2094}}, and {{RFC2627}}.
