The '''Lightweight Extensible Authentication Protocol''' (LEAP) is a proprietary wireless [[LAN]] authentication method developed by [[Cisco Systems]]. Important features of LEAP are dynamic [[Wired Equivalent Privacy|WEP]] keys and [[mutual authentication]] (between a wireless client and a [[RADIUS]] server). LEAP allows for clients to reauthenticate frequently; upon each successful authentication, the clients acquire a new WEP key (with the hope that the WEP keys don't live long enough to be cracked). LEAP may be configured to use TKIP instead of dynamic WEP.

Some 3rd party vendors also support LEAP through the Cisco Compatible Extensions Program.<ref>{{cite web|title=Cisco Compatible Extensions Program|url= http://www.cisco.com/web/partners/pr46/pr147/partners_pgm_concept_home.html |publisher= Cisco |accessdate=2008-02-22}}</ref>
