■Challenge-Response:The authentication server prompts the user with a dynamically generated value — the challenge. The user enters this challenge value on the token card, and the token card generates a response value. The user enters this response value like a password on the handheld computer.

■Event-Synchronous: This system generates and tracks an ordered series of dynamic passwords. The server matches the passwords based on the iteration ID.

Plug-in applications

You can create plug-in applications that contain script commands that you create in order to extend the functionality of the built-in script commands. A plug-in application is a standard .PRC application that is installed on your handheld computer just like any other application. After you install the plug-in application on the handheld computer, the new script commands can be used in a login script.

Plug-in applications have the following characteristics:

■Written in C language

■Compiled into a device executable

■Called properly from a login script

■Able to return control to a login script after it terminates

■Created using a development environment that supports the Palm OS™ software, such as Metrowerks Code Warrior
