A new hybrid cryptosystem for Binding Update in NEMO

Abstract

Traditionally Mobile IP was meant for single mobile nodes, which was then extended to give mobility to networks. This is known as known as Network Mobility (NEMO). Here the Mobile Router (MR) has to intimate to the Home Agent (HA) about its location, using a Binding Update (BU). An acknowledgement is received by MR, during this exchange; an intruder may enter easily because of security lapses. Hence, a security mechanism is required to protect the BU. In this paper a new security method has been introduced to overcome this problem.
