AbstractTwo-tier Security Model for Node Verification is proposed to provide strong security during network communication. This improves the safeguard measures in regards of privacy of sensed information as well as provides authentic communication. Nodes present in the system needs to be communicated in a secured manner; and therefore two level securities are carried out in this proposed scheme. Level 1 includes selection of trustable nodes that includes elimination of malicious node from the communication process by computing node trust ratio. Level 2 includes key generation process for the selected trustable nodes using asymmetric random key generator and removes the illegitimacy nodes completely from communication process. Two-tier Security Model for Node Verification scheme have huge capability in detecting malignant nodes by providing two level securities also tolerates numerous security attacks. Simulation results are shown and proved that projected mechanism has good output with better delivery rates and key matching ratio.
