BOCA PRO16 Reference Guide
With these new features, a link between two modems will be very secure.
No other modem can dial either modem and connect because the third
party will not know the keys of the other users, even if both passwords
are known.
Entering a Key for Each User
• Enter AT#E2 to enable SuperSecure mode
• Select the security menu using AT#S
• Enter the security password to gain access to the security menu
• Set up the modem’s primary DES KEY and Initial Value (IV) as
per standard DES setup
• Select Option 2 to add new users
• Enter the username
• Enter the password to be used by your modem (not necessarily the
same as the password on the modem you are going to dial)
FDo not use a / character in any password, because this character
is reserved
• When the modem prompts you for a command, do not enter a
command because you will not be prompted for the DES KEYS
• Enter the 16 hex digit DES secondary KEY for the user, all 16 digits must
be keyed
• Enter the 16 hex digit DES secondary Initial Value (IV) for the user, all
16 digits must be keyed
• Enter the 2 hex digit Key Encryptor (KE) for the user, both digits must
be keyed
FThe Key, IV and KE can have any value but must be exactly the same
on both answering and originating modems.
FFor maximum security do not use keys or initial values that have easy
to remember values.
FA KE of 00 turns off random key rotation.
• Enter as many users as you wish while in this mode
• Press ENTER at the username prompt to return to the menu
You do not have to turn security on to use SuperSecure. The #E2 option
forces it on always.
• Enter 0 to exit the security menu
