Effectively WPA2 is Wi-Fi Alliance's brand name for 802.11i.Guarantees interoperability certification.Fully conforms with 802.11i as it implements all mandatory features.This setting offers the most compatability but won't guarentee a higher level of encryption if a device falls back to TKIP. It will attempt to use AES if available and fall back to TKIP if not. This is what the encryption standards are for WEP2 (TKIP) and WPA2/802.11i (AES). TKIP is a lower end encryption protocol (WEP2) and AES is a higher end (WPA2/802.11i) encryption protocol. In the context of wireless security this actually means TKIP vs 'AES-based CCMP' (not just AES). Note that TKIP is not directly comparable to AES TKIP is an integrity check, AES is an encryption algorithm.AES is optional in WPA in WPA2 both AES is mandatory, but TKIP is optional.However, some devices allow WPA (not WPA2) with AES (and WPA2 with TKIP).WPA was designed to be used with TKIP (and WPA2 designed to use stronger AES-based).The same key is used by all clients, so may require more work to update.ĭefines the algorithm used for message integrity and confidentiality. home network, without a RADIUS server a pre-shared key (PSK) may be used. This allows individual access to be controlled in a large network. WPA (and WPA2) may operate in enterprise mode, using a RADIUS server to hold per-user keys.Pre-shared (personal) vs Enterprise (RADIUS) As designed, WPA uses TKIP and Michael for message integrity, based on RC4 for encryption.Designed to require only a firmware upgrade (full 802.11i usually requires hardward change).Implements the majority of IEEE 802.11i, but with different headers (so can operate both in same network).2.1 Pre-shared (personal) vs Enterprise (RADIUS).
