Simulation of a Novel Authentication Scheme to Solve DoS Attack in Mobile WiMAX


Objectives: Main Objective of this research is towards the avoidance of Denial of Service (DoS) Attack in Mobile WiMAX. For this a secure authentication mechanism is required and we present a highly secure authentication mechanism. It gives a mutual authentication between Client and Server and the server resources would consume less. Methods/Statistical Analysis: For implementation of this secure authentication, a puzzle approach has been used wherein a puzzle is sent by Base Station to Mobile Station. Unless and until the client do not solve this puzzle, server will not verify its certificates. For the implementation of this work, NS-2 as a simulator, has been used. Where three scenario have been implemented: 1) normal current working scenario of Mobile WiMAX, 2) DoS attack have been simulated without puzzle approach and 3) when under DoS attack with puzzle approach implementation. Findings: The proposed puzzle approach shows an increase of overall throughput of network as compared to the existing report and also the number of secure packets are increasing. It is because of the probability of unauthenticated user becomes almost negligible. Application/Improvements: This research work can be helpful in any of the working environment where security is the most important concern as in the case of defense where availability of network and security of network is always at the highest priority.
