Providing Energy Efficient Security for Mobile Ad hoc Networks

Network coding promises significant benefits in network performance. Transmission cost data; encryption /decryption are the sources of energy consumption in Mobile Ad Hoc Networks. Network coding helps to reduce energy consumption in MANETs, but is weak to provide confidentially and security for global evasdroppers.To provide security for MANETs symmetric key algorithms are not sufficient. This paper introduces new permutation encryption scheme in combination with network coding to increase throughput, reliability and security for MANETs. Such a scheme designed in practice will help in building secure MANET based application.
