%0 Journal Article %T A Novel Approach for Attacks Mitigation in Mobile Ad Hoc Networks Using Cellular Automatas %A Himadri Nath Saha %A Debika Bhattacharyya %A P. K. Banerjee %J International Journal of Ad Hoc, Sensor & Ubiquitous Computing %D 2012 %I Academy & Industry Research Collaboration Center (AIRCC) %X Many security schemes for mobile ad-hoc network(MANET) have been proposed so far but none of them has been successful in combating the different types of attacks that a mobile ad-hoc network often faces. This paper is providing one way of mitigating attacks in mobile ad-hoc networks by authenticating the node who tries to access this network .This scheme has been applied by using cellular automata (CA). Our simulation results show how cellular automata(CA) is implemented for user authentication and secure transmission in MANET. %K Ad hoc network %K User authentication %K Node capturing %K Shared key mechanism %K Cellular automata. %U http://airccse.org/journal/ijasuc/papers/3212ijasuc04.pdf
