16 AES Encryption Upgrade The Motorola PTP 600 Series bridges support link encryption using the NIST approved
Advanced Encryption Standard, HFIPS-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 Motorola
Systems Support Page.
There are two levels of encryption that are available to purchase:
• 128-bit
• 128 and 256-bit
