Integrating mobility, multi-homing and security in universal network

Abstract

In current network, IP address is used to represent both a host's identity and a host's topological location. This overloading makes mobility and multi-homing hard from the security point of view. In this paper we show in universal network how to solve the end-host mobility and end-host multi-homing problems, and introduce a signalling protocol to solve the security problems caused by mobility and multi-homing. Basically, universal network introduces a new architecture, in which AID is used to represent the identity of the host, RID is used to denote the topological location of the host, breaking the fixed binding between identities and locations.
