LEAP, short for Light Extensible Authentication Protocol, has been developed by Cisco Systems, Inc. and builds on Wi-Fi® WEP encryption. It changes the WEP key dynamically during a session to make it less likely that a snooper will be able to derive the key. LEAP uses user ID and password for authentication between a wireless client and a RADIUS server.
CKIP is the original Key Integrity Protocol for LEAP by Cisco Systems, Inc.
