Abstract:

The false data injection attack is a major security threat in Wireless Sensor Network (WSN) since is degrades the network capability. The bandwidth efficient cooperative authentication (BECAN) scheme is used for filtering the false data injection attack. It is used to save energy of sensor nodes in WSN by early detection and filtering of maximum possible injected false data. Source authentication is a critical security requirement in wireless sensor networks to identify attacker nodes that injects false data. Solutions based on Elliptic Curve Cryptography (ECC) have been used for source authentication, but they suffer from severe energy depletion. This results in high computational and communication overheads. Bloom filter based Symmetric-key source authentication scheme exhibits low authentication overhead .This avoids the inherent problems associated with public key cryptography based schemes. The current work demonstrates the efficiency of bloom filter based source authentication using BECAN scheme by comparing ECC and Bloom filter based methods in terms of energy consumption.
