TTLS
Tunnelled Transport Layer Security (TTLS) supports secure user
name/password and mutual authentication. It provides highly
secure transmissions allowing the client to authenticate a
certificate installed on the server and then forms a secure
connection between client and server. The server authenticates
the client over the secured connection when the user provides a
user name and password.
802.1X Certificate Enroller
This utility allows you to request a user certificate from a
certificate server. Once the certificate has been received and
stored on your iPAQ Pocket PC, you can access the network
using one of the 802.1X protocols. Refer to “Manually Entering
New Network Settings” earlier in this chapter for information on
selecting one of these protocols.
To retrieve a certificate:
1. Be sure your Pocket PC has an ActiveSync connection to a
computer on the same network as the certificate server.
2. Tap Start > Settings > System tab > Certificates > Enroll.
3. Complete the on-screen certificate request form by entering
your name, password, and the server to retrieve the certificate
from.
4. Tap the Retrieve Certificate button to download the
certificate from the server. The status box at the bottom of
the screen will indicate whether the attempt to retrieve the
certificate was successful.
NOTE: The enrollment tool is specifically designed to interact
with Microsoft Certificate Servers. Alternate Certificate
Authority servers will require a custom enrollment application
which can be developed using the Embedded Visual C 4.0 tool
and the Software Development Kit for Windows Mobile
2003-based Pocket PCs.
