Abstract

Wireless Sensor Networks (WSN) consist of a large number of sensor nodes equipped with limited computational capacity, memory and battery energy. As sensor nodes in WSN deployed in a hostile and unattended environment, the networks is susceptible to various malicious threats. False data injection is one of them. An adversary may attempt to inject false data containing non-existent events through some compromised nodes causing false alarms at the base station and draining out energy of forwarding nodes. As a result, detection of false data injection in WSN is an important concern. This paper presents a scheme using hash-based short signatures for filtering false data injection in WSN.
