18 AES Encryption Upgrade
The Motorola PTP 600 Series bridges support link encryption using the NIST approved
Advanced Encryption Standard, H
487HFIPS-197UTH. 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 600 Series system. A license key to
enable link encryption can be purchased from your Motorola Point-to-Point Distributor or
Solutions Provider. AES can be activated on receipt of the activation on the
488HMotorola
Systems Support Page.
There are two levels of encryption that are available to purchase:
• 128-bit
• 128 and 256-bit
Option 1 allows the user to encrypt all traffic sent over the wireless link using 128-bit
encryption. Option 2 allows the user to encrypt traffic using either 128 or 256-bit encryption.
The configuration process for both encryption variants is identical except for the selection of
algorithm. The following configuration example is for a 256-bit encryption key.
18.1 Configuring Link Encryption
After purchasing AES encryption for the PTP 600 Series wireless link, 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 600 Series bridge.
18.2 Configuring Link Encryption
After purchasing AES encryption for the PTP 600 Series wireless link, 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 600 Series bridge.
