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. When configuring HP Jetdirect print servers for dynamic encryption, the following options may be provided if supported by the print server: G Basic Encryption. This option provides dynamic WEP encryption and may be used when using selected EAP/802.1x authentication methods LEAP, PEAP, EAP-TLS, EAP-TTLS. G Robust Encryption. This option supports dynamic WPA and WEP encryption. It is used with EAP/PSK authentication, and with selected EAP/802.1x authentication methods PEAP, EAP-TLS, EAP-TTLS. Robust Encryption provides for dynamic WPA and WEP encryption protocols. If WPA dynamic encryption is not supported by your HP Jetdirect wireless print server, EAP/PSK authentication and Robust Encryption selections will not be available.
