Dynamic Encryption - HP jetdirect 175x Administrator's Manual

must be available on all your wireless network devices.
The need for a static WEP key depends on the authentication
method used. For Open System authentication (the factory default
configuration), a static WEP key can be configured but is not
required. For Shared Key or EAP-MD5, a static WEP key must be
configured, and it must match the active key on the other wireless
network devices.
The HP Jetdirect print server can store up to four static WEP keys,
although only one is active at a time. These WEP keys will remain
the same (hence, static) until the network administrator changes
them.
HP Jetdirect wireless print servers support 40/64-bit and
104/128-bit encryption. When configuring a static 64-bit WEP
encryption key, you enter 40 bits of the WEP key. When configuring
a static 128-bit WEP encryption key, you enter 104 bits of the WEP
key. In both cases, 24 IV (Initialization Vector) bits are
automatically added.
The HP Jetdirect wireless print server supports WEP key entry
using 8-bit alphanumeric ASCII characters (0 through 9, a through
z, A through Z) or 4-bit hexadecimal digits (0 through 9, a through
f, A through F). Note that alphanumeric ASCII characters are
case-sensitive; entering an upper- or lowercase character will result
in different WEP key values. If you use hexadecimal characters, you
should ensure that the resulting bit values convert to the allowed
set of alphanumeric ASCII characters. This will allow you to enter
WEP keys on devices that restrict WEP key entry to alphanumeric
ASCII characters only.

Ethernet Compatibility Alliance (WECA). HP Jetdirect IEEE
802.11b wireless print servers are WECA Wi-Fi certified products.

Dynamic Encryption. Depending on your wireless print server
model, the following dynamic encryption protocols are supported:
G dynamic WEP
G
Wi-Fi Protected Access (WPA)
When dynamic encryption is used, encryption keys are periodically
changed automatically and provide enhanced security.
