So we have known for some time now that WEP is little better than no encryption, about a year ago it was found that using TKIP with WPA had a vulnerability to weaken associated implementations of WPA.
Now scientists in Japan have reportedly come up with a break WPA TKIP secured wireless in less than a minute. The specific details have not been fully discussed, but details have been documented here and will be presented at the IEICE in September.
You can read more over at Network World, but the message is clear really if you have the ability you should be using WPA or WPA2 with AES not TKIP.
