13.4 Wireless Link Encryption FAQ
13.1 Encryption Standard Used
The Motorola PTP 500 Series bridges support link encryption using the NIST approved
Advanced Encryption Standard, HFIPS-197
FIPS-approved symmetric encryption algorithm that may be used by U.S. Government
organizations (and others) to protect sensitive information.
13.2 Upgrading for Link Encryption
Link Encryption is not available in the standard PTP 500 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
Systems Support
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.
13.3 Configuring Link Encryption
After purchasing AES encryption for the PTP 500 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 500 Series bridge.
