Technical Reference; Product Specifications-900 Mhz - GE TransNET 900 Reference Manual

The items described above provide sufficient security for a typical MAS
system. For more highly-sensitive applications, system designers should
consider employing application level encryption into their polling protocols
to further protect their systems. Third party software tools are available for
adding encryption, and these should be considered as part of any advanced
encryption scheme.
