ENWW Introducing the HP Jetdirect Print Server 12
Authentication (Wireless Print Servers)
Server-Based Authentication
HP Jetdirect 802.11b wireless print servers support popular 
authentication server-based methods for network access based on 
IEEE 802.1x Extensible Authentication Protocol (EAP), including:   
● LEAP (Lightweight Extensible Authentication Protocol). LEAP 
is a proprietary protocol from Cisco Systems, Inc. It uses 
passwords for mutual authentication between a client and a 
network authentication server. Dynamic encryption keys are 
used for secure communications. 
● PEAP (Protected Extensible Authentication Protocol). PEAP is 
a mutual authentication protocol that uses digital certificates for 
network server authentication and passwords for client 
authentication. For additional security, the authentication 
exchanges are encapsulated within TLS (Transport Layer 
Security). Dynamic encryption keys are used for secure 
communications.
● EAP-MD5 (EAP using Message Digest Algorithm 5, RFC 1321). 
EAP-MD5 is a one-way authentication protocol that 
authenticates the client using a password protected by the MD5 
encryption algorithm. 
● EAP-TLS (EAP using Transport Layer Security, RFC 2716). 
EAP-TLS is a mutual authentication protocol based on 
X.509-compliant digital certificates for authentication of both the 
client and the network authentication server. Dynamic 
encryption keys are used for secure communications. 
● EAP-TTLS (EAP using Tunneled Transport Layer Security). 
EAP-TTLS is an EAP-TLS extension that supports: 
■ mutual authentication through client and server 
X.509-compliant digital certificates, or 
■ one-way authentication through certificate-based server 
authentication followed by tunneled password-based client 
authentication. For additional security, the authentication 
exchanges are encapsulated within TLS (Transport Layer 
Security).
TTLS uses dynamic encryption keys for secure communications.
