  1. Handover Key Hierarchy for Hierarchical Mobile IPv6 Mobility Management (HMIPv6) Hui Deng Zhen Cao

  2. Problem statement • EAP may be used to authenticate the MN to the network in HMIPv6 • How to re-authenticate the MN to the network when the MN handovers within one MAP or across different MAPs • How to avoid a full EAP authentication exchange during each handover

  3. MAP ADC … … AR AN AR AN MN MN MN MN Mapping between HMIPv6 and Handover keying architecture ADMSK LSAP_MK ADMSK: Access Domain Master Session Key LSAP_MK: Link Secure Association Protocol Master Key defined in draft-nakhjiri-aaa-hokey-ps-03

  4. LSAP_MK2 LSAP_MK1 Handover within MAP:push mode

  5. Handover across MAPs:pull mode ADMSK2

  6. Work Item ? • Shall we consider handover keying to HMIPv6?

  7. References • M. Nakhjiri, A Keying hierarchy for managing Wireless Handover security, [draft-nakhjiri-hokey-hierarchy-02], work in progress • M. Nakhjiri, AAA based Keying for Wireless Handovers: Problem Statement, [draft-nakhjiri-aaa-hokey-ps-03], work in progress
