What is spacenet?
Spacenet is a federated authentication system for secure roaming wifi access across hackerspaces.
Why is it useful?
It is useful because it allows secure wifi access anywhere. We all know hackerspaces aren't usually the most harmless networks, this way you get your own session key and your network session will be extremely hard to sniff without a mirror port on the switch. It's also very easy to use once your hackerspace has set it up correctly. So:
- Easy to use
- Works at every connected hackerspace
How does it work?
It works by using WPA2 Enterprise/802.1x. The access point connects to a local RADIUS server for authentication and session key distribution. If the anonymous identity is not something that ends with @your-local-realm.tld it will proxy the request to one of your country's Spacenet RADIUS nodes which will proxy it to the correct home RADIUS server. From that point on a secure TLS connection will be estabilished and the certificate is verified. If this matches, authentication is performed. If the authentication works, this is passed along to the local RADIUS server and a session key will be handed out to the access point and you will have a secure connection.
