Itron Security Manager (ISM)
Users have the option of enabling enhanced security in OpenWay Riva Water pit modules.
Itron Security Manager (ISM) is a feature of the OpenWay Riva system that ensures certain
pit module commands are issued through secure radio communications between the
handheld computer, Mobile Collector, or OpenWay Riva Network.
There are two fundamental security processes used in the OpenWay Riva system to ensure
secured commands are confidential and valid.
• Authentication. Authentication is the process of confirming that an artifact is genuine or
valid. Authentication in the OpenWay Riva water pit module is the process of verifying the
request is from a valid source and in its original form.
• Encryption. Encryption is the process of transforming information to make it unreadable
to anyone who does not have a valid security key. There are two types of encryption:
symmetric and asymmetric. Symmetric encryption uses a shared key to decrypt or
encrypt information. Asymmetric encryption uses a private key to encrypt and a public
key to decrypt. Data transmissions over the network are protected using AES-256
encryption.
Battery life
Powered by four non-replaceable, long-life lithium batteries, the OpenWay Riva pit module
has an expected battery life of 20 years, dependent on use case.
Low Battery
OpenWay Riva water modules include a low battery indicator that helps utilities proactively
plan and manage field module replacements.
Note: Low battery functionality is based on the module's firmware version. For more
information, see OpenWay Riva Water module firmware functionality on page 8.
OpenWay Riva pit module transmission modes
The OpenWay Riva Water pit module is an IPv6 Wisun compliant device that operates in
Mobile Mode or OpenWay Riva Network Mode.
