Mobile IPv6 authentication and authorization baseline

A method of establishing a secured information packet communication between a mobile node on a first network and a home agent on a second network comprising the steps of:

• connecting a mobile node to said first network;
• transmitting a first information packet from the mobile node on said first network, said first information packet containing a first authenticator data element generated using a first algorithm and a first shared secret, said first authenticator data element received by a computer server on the second network;
• generating a second shared secret at said computer server for use by the mobile node and the home agent;
• receiving a second authenticator data element at said mobile node;
• and
• deriving said second shared secret from said second authenticator using an inverse calculation to use to secure information packets transmitted between the mobile node and the home agent.

A set of information packet communications implementing a secure communication protocol between a mobile node and a home agent, comprising:

• a first information packet containing a first authenticator data element generated using a first algorithm processing a first shared secret, said first information packet transmitted from the mobile node;
• a second information packet containing a second authenticator data element generated using a second algorithm processing a second shared secret;
• a third information packet transmitted between the mobile node and the home agent secured using said second shared secret;
• and
• said first shared secret provided by the mobile node and said second shared secret generated by a computer server.
