Formal analysis of the handover schemes in mobile WiMAX networks

An overview of the EAP-based handover procedures of the IEEE 802.16e standard is introduced and their security vulnerabilities are analyzed. Possible solutions for secure handover in IEEE 802.16e networks that guarantee a backward and forward secrecy are described and formally verified using Scyther, a specialized model checker for security protocols. These solutions showed a few drawbacks in the verified procedure and some modifications are proposed for a more secure and efficient handover protocol.
