Quality of service (QoS) and security in Mobile IP networks are becoming significant issues due to an increasing number of wireless devices. For this reason, the Hierarchical Mobile IPv6 (HMIPv6) protocol and the Authentication, Authorization, and Accounting (AAA) protocol are proposed. However this protocol has inefficient authenticating and binding update procedures that limit its QoS. In this paper, we propose a forwarding scheme extension for fast and secure handoff that can reduce a handoff delay while maintaining a security level by a forwarding and session key exchange mechanism. The performance results show that the proposed mechanism reduces the handoff latency up to 10% and the handoff failure rate up to 25% compared to the previous mechanism.
