Securing Against Insider Attacks

e are all creatures of habit; the way we think and the views we take are conditioned by our education, society as a whole, and, at a much deeper level, our cultural memories or instinct. It is sometimes surprising how much the past can unconsciously affect today’s thinking. George Santayana famously observed, “Those who cannot remember the past are condemned to repeat it.” But when it comes to ...

TimingCamouflage: Improving Circuit Security against Counterfeiting by Unconventional Timing

With recent advances in reverse engineering, attackers can reconstruct a netlist to counterfeit chips by opening the die and scanning all layers of original chips. This relatively easy counterfeiting is made possible by the use of the standard simple clocking scheme where all combinational blocks function within one clock period. In this paper, we propose a method to invalidate the assumption t...

Securing AODV Protocol against BlackholeAttacks

Mobile Ad Hoc Networks are autonomous and decentralized wireless systems. MANETs consist of mobile nodes that are free in moving in and out in the network.The nodes can form arbitrary topologies depending on their connectivity with each other in the network. These nodes have the ability to configure themselves and because of their self-configuration ability, they can be deployed urgently withou...
