Is it possible to encrypt the wireless data between hosts and access point? We use TTLS and PEAP and were under the impression that ALL the data when through a secure tunnel but it appears we are wrong and only the authentication process goes through the tunnel. Any way we can set up encryption? Thanks.
Implement WPA or WPA2, this will encrypt ALL data traffic between AP & Client following authentication.
Encryption master keys are unique to every client, change for every packet, update upon roaming and group membership changes (ie, somebody leaves / joins the AP)
Currently, the most secure way of implementing this is WPA2-AES, however WPA-TKIP is still extremely secure (still not cracked to the best of my knowledge) and has wider support from older clients.
