Implementing Network Encryption
In order to implement 802.11i, one must first make sure both that the router/access point(s), as well as all client devices are indeed equipped to support the network encryption. If this is done, a server such as RADIUS, ADS, NDS, or LDAP needs to be integrated. This server can be a computer on the local network, an access point / router with integrated authentication server, or a remote server. AP's/routers with integrated authentication servers are often very expensive and specifically an option for commercial usage like hot spots. Hosted 802.1X servers via the Internet require a monthly fee; running a private server is free yet has the disadvantage that one must set it up and that the server needs to be on continuously
To set up a server, server and client software must be installed. Server software required is a enterprise authentication server such as RADIUS, ADS, NDS, or LDAP. The required software can be picked from various suppliers as Microsoft, Cisco, Funk Software, Meetinghouse Data, and from some open-source projects. Software includes:
- Cisco Secure Access Control Software
- Microsoft Internet Authentication Service
- Meetinghouse Data EAGIS
- Funk Software Steel Belted RADIUS (Odyssey)
- freeRADIUS (open-source)
- SkyFriendz (free cloud solution based on freeRADIUS)
Client software comes built-in with Windows XP and may be integrated into other OS's using any of following software:
- Intel PROSet/Wireless Software
- Cisco ACU-client
- Odyssey client
- AEGIS-client
- Xsupplicant (open1X)-project

Famous quotes containing the word network:
“How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.”
—Gérard De Nerval (1808–1855)
