Wireless AP to cache the results of a full 802.1X authentication so that if a client roamsīack to a wireless AP with which it has previously authenticated, the wireless client PMK CachingĪs a wireless client roams from one wireless AP to another, it must perform a fullĨ02.1X authentication with each wireless AP. Wireless equipment can optionally support PMK caching and preauthentication. To minimize the delay associated with roaming to another wireless AP, WPA2 When a wireless client roams from one wireless AP to another, theĭelay to perform 802.1X authentication can cause noticeable interruptions in networkĬonnectivity, especially for time-dependent traffic such as voice or video-based data This message exchange introduces a delay in theĬonnection process. The pairwise transient keys are used for encryption and data integrity of WPA2.

WEP VS WPA PERSONAL AND ENTERPRISE SERIES

When a wireless client authenticates using 802.1X, there are a series of messages sentīetween the wireless client and the wireless AP to exchange credentials (802.1XĪuthentication) and to determine the pairwise transient keys (the 4-way handshake). WPA2 includes fast roaming techniques such as Pairwise Master Key (PMK) caching and pre-authentication. For example, WPA2 requires support for both TKIP and AESĮncryption. Mandatory security features of the IEEE 802.11i standard that are not already included for The goal of WPA2 certification is to support the additional Wi-Fi Protected Access 2 (WPA2) is a product certificationĪvailable through the Wi-Fi Alliance that certifies wireless equipment as being compatible The IEEE 802.11i standard formally replaces WEP and the other security features of the Office (SOHO) infrastructure mode networks WPA2

WPA-Personal: Uses a preshared key (PSK) for authentication and is designed for small office/home.

WPA-Enterprise: Uses 802.1X authentication and is designed for medium and large infrastructure mode networks.

The Advanced Encryption Standard (AES) for encryption. Known as the Temporal Key Integrity Protocol (TKIP). WPA replaces WEP with a much stronger encryption method Organization of wireless equipment vendors, created an interim standard known as Wi-Fi In the "WPA2" section later in this tutorial, was being finalized, the Wi-Fi Alliance, an While the IEEE 802.11i wireless LAN security standard, which will be discussed Original 802.11 standard, it provides no solution to the weaknesses of the WEP encryptionĪlgorithm. Although 802.1X addresses the weak authentication and key management issues of the
