Encryption applies a specific algorithm to alter its appearance and prevent unauthorized reading.

Decryption applies the algorithm in reverse to restore the data to its original form. Sender and

receiver must employ the same encryption/decryption method to interoperate.

Wired Equivalent Privacy (WEP) is available in two encryption modes: 40 bit (also called WEP 64) and

104 bit (also called WEP 128). The 104-bit encryption mode provides a longer algorithm (better

security) that takes longer to decode (hack) than the 40-bit encryption mode.

Each WLAN (16 WLANs available in total to an access point regardless of the model) can have a

separate security policy. However, more than one WLAN can use the same security policy. Therefore,

to avoid confusion, do not name security policies the same name as WLANs. Once security policies

have been created, they are selectable within the Security field of each WLAN screen. If the

existing default security policy does not satisfy the data protection requirements of a specific WLAN,

a new security policy (using the authentication and encryption schemes discussed above) can be

created.

To enable an existing WLAN security policy or create a new policy:

1. Select Network Configuration -> Wireless -> Security from the access point menu tree.

The Security Configuration screen displays.

2. If a new security policy is required, click the Create button.

The New Security Policy screen displays with the Manually Pre-shared key/No

authentication and No Encryption options selected. Naming and saving such a policy (as

is) would provide no security and might only make sense in a guest network wherein no

sensitive data is either transmitted or received.

However, selecting any other authetnication or encryption checkbox displays a configuration

field for the selected security scheme within the

New Security Policy screen.

3. Use the Name field to define a logical security policy name.

Remember, multiple WLANs can share the same security policy, so be careful not to name

security policies after specific WLANs or risk defining a WLAN to single policy. Motorola

recommends naming the policy after the attributes of the authentication or encryption type

selected (for example, WPA2 Allow TKIP).

NOTE An existing security policy can be edited from the Security Configuration

screen by selecting an existing policy and clicking the Edit button. Use the

Edit Security Policy screen to edit the policy. For more information on

editing an existing security policy, refer to security configuration sections

described in steps 4 and 5.
