Wireless sensor networks are vulnerable to various attacks. Injecting false data attack is one of the serious threats to wireless sensor network. In this paper, adversary reports bogus information to the sink which causes error decision at upper level and energy waste in en-route nodes. Several authentication techniques using en-route filtering and cryptographic techniques are used for preventing such attacks. This paper focuses on the design of RSA based security scheme with on demand routing. On-demand routing protocol is used in this scheme to lower the energy consumption.
