MANET is a dynamic wireless network without any infrastructures.The network is weak and vulnerable to many types of attacks including BlackHole attack.BlackHole node advertises itself as having freshest or shortest path to a specific node to absorb packets.The effect of BlackHole attack on AODV will be addressed in this paper by using cryptography technique for securing route discovery and data transmission.Simulation results using NS2 depict the improvement of packet delivery ratio and network throughput in the presence of BlackHole nodes.
