Wireless Link Encryption

The PTP 400 Series Bridge system supports link encryption using the NIST approved
Advanced Encryption Standard, FIPS-197. This standard specifies AES (Rijndael) as a FIPS-
approved symmetric encryption algorithm that may be used by U.S. Government
organizations (and others) to protect sensitive information.
Link Encryption is not available in the standard PTP 400 Series Bridge. A license key to
enable link encryption can be purchased from your Motorola Point-to-Point Solutions Provider
or Distributor. AES can be activated on receipt of the activation on the
Generator page.

14.1 Configuring Link Encryption

After purchasing AES encryption for the PTP 400 Series Bridge, two new license keys will be
issued, one for each end of the wireless link. The following configuration process gives a step
by step guide to enabling AES link encryption on a PTP 400 Series Bridge wireless link.

14.1.1 License Keys

The first step when configuring link encryption is to enter the new license keys in both PTP
400 Series Bridge wireless units.
Figure 94 shows the license key data entry screen. This screen can only be accessed by the
system administrator. If you do not have access to the PTP 400 Series Bridge system
administration pages, please contact your designated system administrator.
It must be noted that configuring link encryption will necessitate a PTP 400 Series Bridge
service outage. Therefore it is recommended that the configuration process is scheduled
during an appropriate period of low link utilization.
