A SECURED DATA TRANSMISSION METHOD USING ENHANCED PROACTIVE SECRET SHARING SCHEME TO PREVENT BLACK HOLE ATTACKS IN MANETS
E. Karthikeyan · 2014
Mobile Ad hoc Networks consist of mobile nodes which are running randomly. Nodes communicate with each other without any access point. Due to mobility of nodes, network is easily affected by several types of attacks. In particular black hole attack cause packet dropping, misrouting the information from source to destination. To reduce the effect of this attack, we propose a New Enhanced Proactive Secret Sharing Scheme (NEPSSS) to detect the black hole nodes and to ensure the data confidentiality, data integrity and authenticity. In first phase of the proposed algorithm, the detection of black hole attack is achieved using trust active and recommendation of the nodes. In second phase of the work, Enhanced Proactive secret sharing scheme is used to provide the data authentication and integrity. The simulation results shows the proposed algorithm achieves the better packet delivery ratio, misbehaviour detection efficiency, fewer packets overhead and low end to end delay than the existing schemes.
