WPA-PSK

Wi-Fi Protected Access (WPA) is a certification program administered by the Wi-Fi Alliance to indicate compliance with the security protocol created by the Wi-Fi Alliance to secure wireless computer networks. This protocol was created in response to several serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP). PSK means that it is only for Pre-Shared-Key mode

WPA2-PSK

Wi-Fi Protected Access 2 (WPA2) ist die Implementierung eines Sicherheitsstandards für Funknetzwerke nach den WLAN-Standards IEEE 802.11a, b, g und n und basiert auf dem Advanced Encryption Standard (AES). Er stellt den Nachfolger von WPA dar, das wiederum auf dem mittlerweile als unsicher geltenden Wired Equivalent Privacy (WEP) basiert. WPA2 implementiert die grundlegenden Funktionen des neuen Sicherheitsstandards IEEE 802.11i.

WEP

In telecomunicazioni e crittografia il Wired Equivalent Privacy (WEP, dall'inglese privacy equivalente alla rete cablata) è parte dello standard IEEE 802.11 (ratificato nel 1999) e in particolare è quella parte dello standard che specifica il protocollo utilizzato per rendere sicure le trasmissioni radio delle reti Wi-Fi. WEP è stato progettato per fornire una sicurezza comparabile a quelle delle normali reti LAN cablate.

802.11a

IEEE 802.11a-1999 or 802.11a, is an amendment to the IEEE 802.11 specification that added a higher throughput of up to 54 Mbit/s by using the 5 GHz band.

802.11ac

IEEE 802.11ac is a wireless computer networking standard of 802.11, currently under development (Draft 4.0[1]), providing high-throughput wireless local area networks on the 5 GHz band.

802.11b

802.11b has a maximum raw data rate of 11 Mbit/s and uses the same media access method defined in the original standard. 802.11b products appeared on the market in early 2000, since 802.11b is a direct extension of the modulation technique defined in the original standard. The dramatic increase in throughput of 802.11b (compared to the original standard) along with simultaneous substantial price reductions led to the rapid acceptance of 802.11b as the definitive wireless LAN technology.

802.11g

This works in the 2.4 GHz band (like 802.11b) but operates at a maximum raw data rate of 54 Mbit/s, or about 19 Mbit/s net throughput. 802.11g hardware is fully backwards compatible with 802.11b hardware.

802.11n

802.11n is a proposed amendment which improves upon the previous 802.11 standards by adding multiple-input multiple-output (MIMO) and many other newer features. Though there are already many products on the market based on Draft 2.0 of this proposal, the TGn workgroup is not expected to finalize the amendment until November 2008.
