WTLS
Wireless Transport Layer Security (WTLS) is the security layer of the WAP that
provides confidentiality, data integrity, and authentication for WAP services.
WTLS allows the client and server to achieve authenticated and encrypted
communication so that wireless transactions remain secure.
WTLS is an optional security feature that you can load onto your handheld when
you use the desktop software’s Application Loader tool. If your service provider
or network operator requires WTLS for secure Browser connections, you must
load WTLS onto your handheld. Refer to the
Application Loader Online Help
for more
information on loading additional handheld applications.

To configure the WTLS default settings.

1. On the Home screen, click the Options icon. The Options screen appears.
2. Click WTLS. The WTLS screen appears. Set the Encryption Strength and
Prompt For Server Trust fields to your preference.
3. Click the trackwheel to view the menu. Click Save. You return to the Options
screen.
Contact your service provider or network operator for more information on
WTLS and available services.
