HMIPv6 bootstrapping is valid for both a mobile node operating in a home network and a mobile node roaming in a visited network, in the former case using the home network AAA infrastructure and in the latter case using the visited The entire AAA infrastructure where the network is linked with the home network.
[0059] Instead of establishing a security association and distributing security keys between the MN and the MAP by employing a public key infrastructure (PKI), it is preferable to perform authentication and authorization of HMIPv6 services based on the AAA infrastructure, for example conveyed as HMIPv6 via the AAA infrastructure HMIPv...
