Group Domain of Interpretation (GDOI) GROUPKEY-PUSH
Acknowledgement Message
Abstract
The Group Domain of Interpretation (GDOI) includes the ability of a
Group Controller/Key Server (GCKS) to provide a set of current Group
Member (GM) devices with additional security associations (e.g., to
rekey expiring security associations). This memo adds the ability of
a GCKS to request that the GM devices return an acknowledgement of
receipt of its rekey message and specifies the acknowledgement
method.
