System Configuration
uses TKIP unicast data encryption keys for WPA clients and WEP
unicast keys for WEP clients. The global encryption key for
multicast and broadcast traffic must be the same for all clients,
therefore it restricts encryption to a WEP key.
When access is opened to both WPA and WEP clients, no
authentication is provided for the WEP clients through shared
keys. To support authentication for WEP clients in this mixed
mode configuration, you can use either MAC authentication or
802.1X authentication.
Advanced Encryption Standard (AES) Support: WPA specifies
AES encryption as an optional alternative to TKIP and WEP. AES
provides very strong encryption using a completely different
ciphering algorithm to TKIP and WEP. The developing IEEE
802.11i wireless security standard has specified AES as an
eventual replacement for TKIP and WEP. However, because of
the difference in ciphering algorithms, AES requires new
hardware support in client network cards that is currently not
widely available. The access point includes AES support as a
future security enhancement.
