>We need WiFi that is open and encrypted at the same time!
There is currently no WiFi protocol that allows anybody to join the network, while using link-layer encryption to prevent each network member from eavesdropping on the others. But such a protocol should exist.
It boggled my mind, repeatedly, when I discovered that non-password-protected wireless networks don't generate a unique encryption key for each connection. Boggle, I say. Sure, public key cryptography used to be too computationally expensive, but not any more. And even if it were, Diffie-Hellman has been around for quite a while, go ahead and use symmetric keys.
What the hell is wrong with our standards groups? And hardware manufacturers? There are trivial solutions to this, why haven't they pushed them?
