802.1x with Shared Key Authentication
Shared key authentication, part of the Wired Equivalency Privacy (WEP) algorithm, provides a basic means of data encryption to improve data security for a Wireless LAN (WLAN). The shared key algorithm performs data encryption and decryption. A wireless device with a valid shared key is allowed to associate with the WS 2000 Wireless Switch and access services on the wired LAN.
Using shared key authentication, an administrator configures mobile units (MUs) and the WS 2000 Wireless Switch to share the same key. The MU authenticates by presenting the key to a WS 2000 Wireless Switch. The switch examines the key, and uses it to perform a checksum, or
The WS 2000 Wireless Switch uses shared key authentication when there is no RADIUS server on the wired LAN.
Kerberos Authentication
The Kerberos authentication service protocol (specified in RFC 1510) provides a secure means for authenticating users/clients in a wireless network environment.
With Kerberos, a client (generally either a user, a service, or a user requesting any number of network services) within the Kerberos Realm sends a request for a ticket to the Key Distribution Center (KDC). The KDC creates a
The KDC operates in a Master or a Slave capacity. The Master KDC maintains the master database file that contains all of the user authentication information. This information includes the user’s name, password, and authorization level. This authorization level determines what network services the user has access to.
The Slave KDC acts in a backup capacity to the Master KDC. Database information propagates from the Master KDC to the Slave at regular intervals. If the Master KDC fails, the Slave KDC resumes ticket granting services until the problem causing the Master KDC to fail is resolved. The Slave KDC has no database administration privileges, which are reserved for the Master KDC.
