Transport Layer Security-based Mobile IPv6 Security Framework for Mobile
                    Node to Home Agent Communication
                    draft-ietf-mext-mip6-tls-03.txt

Abstract

   Mobile IPv6 signaling between a mobile node and its home agent is
   secured using IPsec.  The security association between a mobile node
   and the home agent is established using IKEv1 or IKEv2.  The security
   model specified for Mobile IPv6, which relies on IKE/IPsec, requires
   interaction between the Mobile IPv6 protocol component and the IKE/
   IPsec module of the IP stack.  This document proposes an alternate
   security framework for Mobile IPv6 and Dual-Stack Mobile IPv6, which
   relies on Transport Layer Security for establishing keying material
   and other bootstrapping parameters required to protect Mobile IPv6
   signaling and data traffic between the mobile node and home agent.
