Proprietary and Confidential
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
system.
There are two fundamental security processes used in the OpenWay Riva system to ensure confidentiality and
validity of secured commands.
• 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 a 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.
Enabling OpenWay Riva Water Pit Module Security
Each pit module ships from the Itron factory with a utility factory security key. The presence of this utility
factory key does not enable security. To utilize the module's security feature, the installer must use an Itron
programming device (FC300) that is configured with the corresponding security key for that particular pit
module. Initial key exchange commands are secured using the utility factory key. For more information about
programming the pit module, see the FDM Endpoint Tools Mobile Application Guide (TDC-0934).
Battery Life
The OpenWay Riva Water Pit Module is powered by two non-replaceable, long-life lithium batteries, and has
an expected battery life of 20 years when the pit module operates in default mobile operating mode. If the pit
module is programmed for hard to read mobile mode, the battery life is reduced to 12 years. To proactively
indicate the battery has reached a <10% useful battery life, a Low Battery Flag is set to indicate a low battery
warning and alert the utility of an impending battery failure.
OpenWay Riva Water Pit Module Transmission Modes
The OpenWay Riva Water Pit Module can be set to transmit in Standard Mobile/Handheld Mode (factory
default setting), Mobile High Power Mode, Hard-to-Read, or Audit Mode.
• Mobile and Handheld Mode. In Mobile and Handheld Mode:
• the pit module transmits a medium-powered SCM+ message every 10 seconds.
• (Optional) Mobile High Power Mode. The pit module transmits a high-powered SCM+ RF message
every 60 seconds.
• (Optional) Hard to Read Mobile Mode. The pit module transmits a high-powered SCM+ RF message
every 30 seconds. The hard-to-read Mobile Mode should only be used for exceptionally hard-to-read
locations as this mode reduces battery life significantly.
Note The OpenWay Riva Water Pit Module's battery life is significantly affected in hard to read mobile
mode.
