Comment Per-client encryption: WEP vs WPA (Score 1) 332
One important caveat: this would be useless if the access point is using WEP, which uses the same key to encrypt each client's traffic. It would be trivial to modify Firesheep or any other tool to be able to overcome this. My understating is that WPA is somewhat better since it uses the pre-shared key + a per-session key, though that per-session key could still be sniffed if the attacker captured the handshake when the target first connects. So neither option is secure but WEP would just be snake oil and little better than clear-text.
