 WPA (Wi-Fi Protected Access) — usually used for the larger Enterprise environment, it uses
a RADIUS server and TKIP (Temporal Key Integrity Protocol) encryption (instead of WEP
encryption which is disabled). TKIP uses128-bit dynamic session keys (per user, per session,
and per packet keys).
 WPA-PSK (Wi-Fi Protected Access – Pre-Shared Key) — WPA for home and SOHO
environments also using the same strong TKIP encryption, per-packet key construction, and
key management that WPA provides in the enterprise environment. The main difference is
that the password is entered manually. A group re-key interval time is also required.
