Authentication Authentication is used to validate the identification of each device or computer that is attempting to communicate. The authentication method used on a wireless network is decided during network design and is primarily based on network security requirements. Consequently, the authentication method is closely associated with encryption options also used on the network. The authentication methods supported by the HP Jetdirect wireless print servers include: Open System, Shared Key, EAP/802.1x, and EAP/PSK. Open System. Open System authentication is used when positive validation of a device's identity is not required for network access. If a device is configured for Open System authentication, then any other device or Access Point can authenticate with it. Open System authentication is the factory-default authentication method configured on HP Jetdirect wireless print servers. While Open System authentication virtually allows open access to a device, data security can still be implemented for the device using encryption. For more information, see Encryption. Note If the print server is configured with Open System authentication while the network requires EAP authentication, the Jetdirect configuration page will indicate a Ready status with an Authentication Failed message. Shared Key. Shared Key authentication is used when a standard level of validation for a device's identity is required before network access is permitted. Shared Key authentication requires that WEP security be implemented on all wireless network devices. In Shared Key authentication, a secret WEP key must be independently configured on each wireless device (that is, the same key is shared by the devices on the network). During the authentication process, a comparison is made between a transmitted challenge and an encrypted and decrypted response. An appropriate match must occur before access is allowed. For information on WEP keys, see WEP Security. ENWW HP Jetdirect 802.11b Wireless Print Servers 258

Authentication

Authentication is used to validate the identification of each device

or computer that is attempting to communicate. The authentication

method used on a wireless network is decided during network

design and is primarily based on network security requirements.

Consequently, the authentication method is closely associated with

encryption options also used on the network.

The authentication methods supported by the HP Jetdirect wireless

print servers include:

Open System

Shared Key

EAP/802.1x

, and

EAP/PSK

Open System.

Open System authentication is used when positive

validation of a device's identity is not required for network access.

If a device is configured for Open System authentication, then any

other device or Access Point can authenticate with it. Open System

authentication is the factory-default authentication method

configured on HP Jetdirect wireless print servers.

While Open System authentication virtually allows open access to

a device, data security can still be implemented for the device using

encryption. For more information, see

Encryption

Note

If the print server is configured with Open System

authentication while the network requires EAP

authentication, the Jetdirect configuration page

will indicate a Ready status with an Authentication

Failed message.

Shared Key.

Shared Key authentication is used when a standard

level of validation for a device's identity is required before network

access is permitted. Shared Key authentication requires that WEP

security be implemented on all wireless network devices. In Shared

Key authentication, a secret WEP key must be independently

configured on each wireless device (that is, the same key is shared

by the devices on the network). During the authentication process,

a comparison is made between a transmitted challenge and an

encrypted and decrypted response. An appropriate match must

occur before access is allowed. For information on WEP keys, see

WEP Security.
