Mutually authenticated key agreement protocol based on chaos theory in integration of internet and MANET

Abstract

Integrated Internet MANET (IIM) is a network which is formed by the interconnection of the internet and mobile ad hoc network. IIM suffers from many security issues due to open wireless medium and lack of mutual authentication. Mutual authenticated key agreement technique is used to securely agree on session key between communicating entities. In order to provide mutual authentication between mobile node and a fixed node in IIM, one must overcome two problems i.e. key management and computational cost. The strength of any security algorithm depends on its key management technique. We propose a method to provide mutual authentication between communicating entities using chaos theory. It overcomes the key management cost by avoiding modular exponentiation and scalar multiplications. Through extensive simulation analysis, we conclude that the proposed method provides a better approach towards security and protection of data from malicious nodes with minimum overhead in IIM.
