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…
Building construction machinery and equipment — Concrete mixers — Part 1: Commercial specifications
This document establishes the content for commercial literature for concrete mixers used either as individual machines on building sites or as components of batching plants.
Definitions refer to whole machines, their structure and parameters.
The commercial specifications establish technical characteristics of the whole machines and their components.
