Secure TORA: Removal of Black Hole Attack Using Twofish Algorithm
N. Venkatadri, K. Ramesh Reddy · 2016
Ad Hoc wireless network is a type of wireless network, in which there is no any fixed infrastructure. Devices in Ad Hoc network can move around the network within a given range. Currently most of the transactions are performed through the computer networks so they are more susceptible to many physical security threats. One of the major DOS Attacks that degrade the performance of the whole MANET is Black Hole attack. In the presence of black hole attack, nasty nodes are not forward the packets rather they drop packets. In this work, black hole attack is detected and eliminated through implementing Digital Signature with Twofish Algorithm. We modified on-demand routing protocol Temporally Ordered Routing Algorithm (TORA) and named it as STORA. Our proposed STORA performs well under normal conditions and under black hole attack than original TORA.
