Security
Make sure that the metrological seals and product casing is not damaged in order
to have correct metrological operation and data security.
Privacy
Honeywell can read non-personal data from a returned meter for quality control
and diagnostics through a physical connection and via the display menu.
The data will not be forwarded to a third party. Honeywell cannot access the data
by means of a remote interface.
Key management
The meter comes with secure keys loaded in the factory. All keys are 128-bit
length AES symmetric keys. It is recommended that the keys must be changed
with customer-specific keys after meters are installed. Honeywell NetSense
provides a mechanism for OnDemand key replacement to meters once they
appear in NetSense after meter installation.
The meter supports management and installer roles, a management client can
change both management and installer keys and an installer can change just the
installer key.
The meter keys must be periodically changed. Honeywell NetSense provides a
mechanism for periodic key replacement to all meters. Please refer to Honeywell
NetSense documentation for further details.
The key management and change must happen in a secure environment and the
newly generated keys must be safely stored in a secure database.
Netsense - Connexo NetSense is a powerful enterprise application that serves as the
utility command console for rapid, reliable deployment and operation of the EnergyAxis
System. It manages, monitors, and provides robust reporting capabilities for the utility
smart grid communications and network elements
Warning! LOSS OF METER KEYS WILL MAKE THE PRODUCT COMPLETELY UNUSABLE.
If Honeywell NetSense software is not used for managing AC-250NXS meters,
please contact Honeywell for details on key management.
