Resilient system for secure sharing of information against false data injection attack

摘要

A Wireless Sensor Network (WSN) is a collection of sensor nodes which is deployed randomly in the environment to monitor the conditions. Cyber-Physical Networked System (CPNS) utilized a public key cryptography here they utilized MAC (Message Authentication Code). The existing En-route Filtering plan utilizes same key for sender and beneficiary furthermore utilized for measuring the genuine report. A Polynomial-based Compromise-Resilient En-route Filtering plan (PCREF) is proposed to channel the false information infused in the middle hub. PCREF utilizes two sorts of polynomial which has been gotten from the primitive polynomial: Check Polynomial and Authentication Polynomial. PCREF uses hybrid connection instead of forwarder node used in CPNS. Rivest-Shamir-Adleman (RSA) techniques are used to assign keys for each and every node in the network. It has public and private keys. Each node in the network has its own ID and it plays a vital role in sharing information with the sink node. So it is harder for attacker to compromise the node in the network. By this technique false data injection attack can be avoided.
