Configuring Security On the CK61

This section explains how to configure wireless security on your

CK61. If you choose not to use security, see “Disabling Security” on

page 63.

Configuring Security on the Wireless Network

Your wireless adapter (network interface card) connects to wireless

networks of two types: infrastructure networks and adhoc networks.

• Infrastructure networks connect you to your corporate network

and the internet. Your computer establishes a wireless connection

to an access point, which links you to the rest of the network.

• Ad-hoc networks are private networks shared between two or more

clients, even without an access point.

Each wireless network is assigned a name (or SSID) to allow multiple

networks to coexist in the same area without infringement.

Intermec recommends using security measures with wireless networks

to prevent unauthorized access to your network and to ensure the

privacy of transmitted data. These elements are required for secure

networks:

• Authentication by both the network and the user

• Authentication is cryptographically protected

• Transmitted data

There are many schemes available to implement these features. Use

the following tables to understand the common terminology for

wireless network security.

Encryption Terminology

Acronym Description

AES Advanced Encryption Standard. A block cipher, a type of

symmetric key cipher that uses groups of bits of a fixed length

- called blocks. A symmetric key cipher is a cipher using the

same key for both encryption and decryption. As implemented

for wireless, this is also known as CCMP, which implements

AES as TKIP and WEP are implementations of RC4.
