Abstract: Quality of service (QoS) and security in Mobile IP networks are becoming significant issues due to an increasing number of wireless devices[1]. For this reason, the Hierarchical Mobile IPv6 (HMIPv6) protocol[2] and the Authentication, Authorization, and Accounting (AAA) protocol[3] 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.
