Management Security Option
Note: The Management Security feature is not provided with standard VMS
installations, and is available only upon request and through an autho-
rized agent.
This feature requires the use of a specially programmed Crypto-Key.
Management Security is an optional software module for the VMS that protects
the M&C messages that pass between SLM-5650A modems and the VMS over
exposed LAN/WAN segments within the network. Encryption key management
operates through manual key distribution, with M&C keys entered in the VMS
and at each modem associated with the VMS.
A Switching encryption option for VESP is included in this security feature as
well.
Encryption is based on the FIPS approved Advanced Encryption Standard
(AES), a block cipher algorithm, using a 128-bit fixed block size and 256-bit
keys.
1. Open the Properties window for the VMS Server and select the Encryption
dialog, as shown in figure 3-131.
