Proxy Signcryption Algorithm for Interdomain Authentication in Wireless Mesh Networks

Abstract Authentication delay is main requirement for handoff in wireless mesh networks. When mobile client moves from one domain to another. In order to solve the problems, we propose an algorithm for handoff in Wireless Mesh Networks. pre-authentication are done by mobile station itself up to the next access point. Neighbor graph is used for maintaining and dynamically identifying the mobile topology of the network. Proxy signcryption scheme is applied between the Mesh Node (MN) and mobile client (MC) for the period of inter-domain authentication. To make sure security, the authentication messages are encrypted while transmitted between mobile client and mesh nodes and signed in an integrated fashion such that the communicated message is expressed as signcrypted. Simulation’s output shows, that the algorithm strengthen security of network .
