Security
Users have the option of enabling enhanced security in Cellular 500W Pit Modules. Itron
Security Manager (ISM) is a feature of the OpenWay
®
system that ensures certain pit module
commands are issued through secure radio communications between the handheld
computer, Mobile Collector, or OpenWay Network.
There are two fundamental security processes used in the OpenWay 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 Cellular 500W 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.
Transmission Modes
The Cellular 500W Pit Module is an IPv6 Wisun compliant device that operates in Mobile
Mode or Network Mode.
Mobile Mode
In Mobile Mode, the module transmits every nine seconds over multiple RF channels to report
on:
■
meter register value
■
cut cable or communication error event
■
reverse flow (encoder version selected)
■
system leak status
■
low battery indicator
