3 CPDP Security Features

Modem security management

Two types of modem security are provided for the DART 200:

Personal Identification Number (PIN) - Protects against unauthorized use of the CDPD network. A PIN can be required before the modem can gain access to the CDPD network

Service Provider Key (SPK) - Protects against modem operating parameters being altered. An SPK is mandatory before making changes

The use of the PIN can be required by the service provider, although currently none do. If not required by the carrier, you have the option of requiring it, or leaving it disabled (this is the modem default). However, the use of the SPK is mandatory and cannot be disabled.

The intent of the security management feature is to provide a layer of control at the end-user level, in addition to CDPD network authentication services, to aid in the prevention of unauthorized access to the network.

Table 3-1 summarizes the DART 200’s PIN management system. There are four keys and six AT commands, three of which will only function when in service provider mode, involved in the total process.

Description

 

 

PIN

Prevents unauthorized access to the CDPD network by

 

blocking commands that access the network, including the

 

registration command (AT\R) and the dial command (ATD).

 

To use these commands an authorized PIN and the AT*E

 

command are required. If the PIN is entered incorrectly three

 

times in a row it becomes BLOCKED. The default is PIN not

 

required.

 

 

PIN

The AT*U command temporarily enables the PIN when it

Unblocking

becomes BLOCKED, allowing it to reset or change to a new

Key

value. BLOCKED status is permanently cleared by the AT^C

 

command, and PIN values are reset or changed by the AT\P

 

command. If the PIN unblocking key is entered incorrectly 10

 

times in a row, it also becomes BLOCKED. The BLOCK of

 

the PIN Unblocking Key is also cleared by the AT^C

 

command.
