Is it possible to implement WPA encrypted wireless network without any predefined secrets like PSK?
For example: a coffee shop with WPA-PSK protected network. Everyone who has ever been in the coffee shop knows the passphrase for their network, so they can also capture all the handshakes and use them to decrypt all the traffic, right?
So could we just remove the redundant PSK? So that handshakes would still be the weak point but all the rest of traffic would still be encrypted?
