Security

PTP 800 provides optional 128-bit and 256-bit encryption using the Advanced
Encryption Standard (AES).
AES upgrades are supplied as an access key. The access key authorizes the
generation of a new license key that will enable AES operation for one CMU. Two
access keys are needed to operate AES on a link. The upgrade is applied by
entering an access key together with the MAC address of the target CMU into the
PTP License Key Generator web page, which may be accessed from
http://www.motorola.com/ptp/support.
This web page generates a new license key that must be installed on the CMU.
When the license key is installed, the CMU must be rebooted before AES can be
enabled. Once applied, the AES upgrade is bound to a single CMU and is not
transferrable.
AES encryption in PTP 800 is based on pre-shared keys. An identical key must be
entered at each end of the link.
