One Time Secret Key Mechanism for Mobile Communication

Mobile communication is playing a vital role in the current technical world and becoming more popularand prevalent across the world everyday at one end and many security problems are arising at the otherend. To overcome these security problems many security mechanisms for mobile communications havebeen introduced in the literature. Among these mechanisms, authentication plays a quite important rolein the entire mobile network system and acts as the first defense against attackers since it ensures thecorrectness of the identities of distributed communication entities before they engage in any othercommunication activity. In this paper, we propose a novel authentication mechanism, called the nestedone-time secret mechanism, efficient for mobile communication environment which mainly focus on thesecurity issues of mobile communication and also overcome the problem of high computational andcommunication cost with good result in reducing the cost of computational and communication cost fromthe existing system, the cost reduction is possible by reducing the usage of the memory for key generationin the proposed scheme and the experimental result of the proposed scheme is also been showed in thispaper.
