multi valent
A delegator may have multiple delegates, thereby enabling elastic horizontal scalability. Multiple delegates from a single delegator. Furthermore, each delegate may act as a delegator for its own delegates to form a nested delegation tree.
This allows mapping key management infrastructures to any hierarchically structured organization's computing infrastructure. With this construction, both security and performance trade-offs may be made as appropriate. Such an extended delegation setup we call a multivalent key management infrastructure.
