Securing Data with Selective Encryption Based DAC Scheme for MANET

MANETs consist of mobile nodes which can any time enter or exit from the network [16]. The no central admin set up of the MANET makes it more prone to attacks [5]. Sending much more secured data than any other networks is verily needed in MANETs since the mobile nodes consume a lot of energy for capturing signals and cryptanalysis of messages. Here we are presenting a security scheme that adorns selective encryption strategy and encrypts selective bit positions instead the entire data set. The scheme needs less computation capability while providing adequate security to the MANET nodes [15]. It provides better security compared to the existing selective encryption algorithms. Thus we manage safety as well energy conservation of mobile nodes.
