SNMP-USM-DH-OBJECTS-MIB Table View

This table augments and extends the usmUserTable and provides
4 objects which exactly mirror the objects in that table with the
textual convention of 'KeyChange'.  This extension allows key
changes to be done in a manner where the knowledge of the current
secret plus knowledge of the key change data exchanges (e.g. via
wiretapping)  will not reveal the new key.

usmDHUserKeyEntry row .1.3.6.1.3.101.1.1.2.1

A row of DHKeyChange objects which augment or replace the
functionality of the KeyChange objects in the base table row.

A table of mappings between zero or more Diffie-Helman key
agreement values and entries in the usmUserTable.  Entries in this
table are created by providing the associated device with a
Diffie-Helman public value and a usmUserName/usmUserSecurityName
pair during initialization. How these values are provided is
outside the scope of this MIB, but could be provided manually, or
through a configuration file.  Valid public value/name pairs
result in the creation of a row in this table as well as the
creation of an associated row (with keys derived as indicated) in
the usmUserTable.  The actual access the related usmSecurityName
has is dependent on the entries in the VACM tables.  In general,
an implementor will specify one or more standard security names
and will provide entries in the VACM tables granting various
levels of access to those names.  The actual content of the VACM
          
table is beyond the scope of this MIB.
          
Note: This table is expected to be readable without authentication
using the usmUserSecurityName 'dhKickstart'.  See the conformance
statements for details.

usmDHKickstartEntry row .1.3.6.1.3.101.1.2.1.1

An entry in the usmDHKickstartTable. The agent SHOULD either
delete this entry or mark it as inactive upon a successful SET of
any of the KeyChange-typed objects in the usmUserEntry or upon a
successful SET of any of t…
