Without an Authentication Server For small office networks that do not have an authentication server, HP Jetdirect wireless print servers support network authentication using Extensible Authentication Protocol with a Pre-shared key (EAP/PSK). Using a pass-phrase entered by the user, the print server generates a pre-shared key used for network access and communications. When configured for EAP/PSK authentication, the print server uses Wi-Fi Protected Access (WPA) dynamic encryption protocols for wireless communications. Encryption HP Jetdirect 802.11b wireless print servers support static WEP (Wired Equivalent Privacy) encryption. For static WEP encryption, a network WEP key of fixed length (40/64-bit or 104/128-bit) is shared by each device on the network. Depending on your wireless print server model, the following dynamic encryption protocols are supported: G dynamic WEP G Wi-Fi Protected Access (WPA) Note If not supported by your HP Jetdirect wireless print server, EAP/PSK authentication and Robust encryption will not be displayed as a selectable configuration option. When dynamic encryption is used, encryption keys are periodically changed automatically and provide enhanced security because they will likely change before someone can decipher them. In dynamic WEP encryption, each device on the wireless network is assigned a different encryption key that expires at preset intervals and is then replaced. WPA encryption is an enhanced version of dynamic WEP and offers improved security. For example, new encryption keys are generated for fixed amounts of data (10 kilobytes) transmitted by a device on the network. ENWW Introducing the HP Jetdirect Print Server 13
