On Reduced Cost and Attack Proof Secure Authentication for Multi-Operator domain of WMN using the Asymmetric Cryptographic Technique

Abstract

Wireless mesh network (WMN) is considered to be an evolving technique because of selfconfiguration and adaptive features, it supports large scale network especially in an organization and academics. As with any network, communication among nodes plays an important role, when two nodes in a network communicate with each other via the internet, secure authentication is an imperative challenge. In literature, there are many approaches that have been suggested to deliver a secure authentication between nodes in wireless mesh network (WMN), however, all these outlines contain some disadvantages i.e. management cost of the public key and system complexity. In this paper, a SAWMN approach is proposed which overcomes these drawbacks and provides an efficient authentication to the mesh clients. Further, SAWMN results have been shown simulated on AVISPA SPAN to ascertain the authenticity of the proposed approach. The broker is a reliable third party which lives in the first tier. Broker consist a private key generator, whose function is to generate a private key. Gateway lives in the second tier and router lives in the third tier. Both gateways as well as router are considered as a trustworthy node because of their less mobility. Any node willing to enter into the network, it has to submit its own identity (identity of any node act as the public key of that node) to the broker and broker hand over private key (by giving identity as an input to the private key generator) to that node. If the newly entered node is the router or gateway, instead of private key it can also send a ticket and its own signing rights to them. Now onwards both gateway and router possess the same functionality of the broker. This technique is formally verified on AVISPA SPAN, which shows that there is no attack is possible and private key is not forgeable. SAWMN (Secure Authentication in Wireless Mesh Network) reduces the overall system complexity by not explicitly managing the public keys and it also efficiently works in real time environment. Our suggested proposed approach extend above discussed technique to accomplish the authentication procedure in Inter-domain and Intra domain. As a result, we have assessed the performance of the proposed design in terms of Authentication cost, Encryption cost, Key validation, Key Generation, Throughput and System Delay, which indicates our scheme more efficient than other schemes.
