Information security — Key management — Part 5: Group key management
1 Scope
This document specifies mechanisms to establish shared symmetric keys between groups of entities. It defines:
— symmetric key-based key establishment mechanisms for multiple entities with a key distribution centre (KDC); and
— symmetric key establishment mechanisms based on a general tree-based logical key structure with both individual rekeying and batch rekeying.
It also defines key…
