Chapter 2 — Connecting and Configuring the CK61

CK61 Handheld Computer User’s Manual With Windows CE 45

The CK61 provides three types of security for your wireless network:

Wi-Fi Protected Access 2 (WPA2/802.11i), WPA, and WEP. 802.1x

should be referred to as an authentication method used for WPA and

WPA2. Another authentication method for WPA and WPA2 would be

the Pre-Shared Key (PSK).

Choosing Between Microsoft and Funk Security

Before you can implement a security solution on the CK61, you need

to choose between Microsoft and Funk security:

• By default, Funk security is enabled. It provides everything you get

with Microsoft security plus the addition of Cisco Compatible

Extensions features. It also provides additional authentication

types like EAP-TTLS, LEAP, and EAP-FAST.

EAP-TLS Transport Layer Security. Based on the TLS (Transport Layer

Security) protocol widely used to secure web sites. This

requires both the user and authentication server have

certificates for mutual authentication. While cryptically

strong, this requires corporations that deploy this to maintain

a certificate infrastructure for all users.

LEAP Lightweight Extensible Authentication Protocol. Also known

as Cisco-Wireless EAP, provides username/password based

authentication between a wireless client and a RADIUS server.

In the 802.1x framework, traffic cannot pass through a

wireless network access point until it successfully

authenticates itself.

EAP-TTLS Tunneled Transport Layer Security. This protocol provides

authentication like EAP-TLS but does not require certificates

for every user. Instead, authentication servers are issued

certificates. User authentication is done using a password or

other credentials that are transported in a securely encrypted

“tunnel” established using server certificates.

EAP-TTLS works by creating a secure, encrypted tunnel

through which you present your credentials to the

authentication server. Thus, inside EAPTTLS there is another

inner authentication protocol that you must configure via

Additional TTLS Settings.
