An enhanced security system Using multimodal biometrics For hierarchical mobile ad hoc Networks

Abstract

The main objective of this research work is to design and develop a newlineCancelable Multimodal Biometric based Secured Authentication System newlineCMBSAS for hierarchically clustered Mobile Ad hoc Network MANET newlineenvironment which needs high security Our CMBSAS provides different newlinesecurity services such as data confidentiality sender authentication and newlinereceiver authorization using different biometric modalities Additionally newlinemessage integrity cryptographic key revocability and biometric privacy are newlinealso provided using various algorithms in our system This thesis also newlineanalyses the performance of our system using various performance metrics newlineand implementing it in a MANET environment to prove that our system is newlinemore efficient than other systems newlineWith the rapid evolution of wireless technologies the reliance of newlineMANETs to carry mission critical information is rapidly growing and it leads newlineto the development of many security systems This is especially important in a newlinescenario where strategic and tactical information is sent Therefore the ability newlineto achieve a highly secure authentication has become more essential in newlineapplications which need high security The ultimate goal of a security solution newlineof MANET is to provide security services such as authentication, newlineauthorization confidentiality integrity and availability to the mobile users newlineDue to the overhead present in the traditional algorithms such as key newlinedistribution problem they are not suitable for an ad hoc environment which newlinehas low processing power and limited battery power Also these algorithms newlineare not sufficient for more delicate and complex applications newline
