Wireless Sensor Network consists of spatially distributed autonomous sensors to monitor environmental conditions of the earth The development of wireless sensor networks was motivated by military applications such as battlefield surveillance Wireless Sensor Networks WSN are deployed at critical places like surveillance monitoring airports battlefield applications hence securing wireless sensor networks is a very challenging task Following are the Security Requirements in Wireless Sensor Networks 1 Confidentiality Confidentiality requirement is required to ensure that sensitive information is well protected and not revealed to unauthorized third parties The confidentiality objective helps to protect information traveling between the sensor nodes of the network or between the sensors and the base station from disclosure since an adversary having the appropriate equipment may eavesdrop on the communication By eavesdropping the adversary could overhear critical information such as sensing data and routing information Based on the sensitivity of the data stolen an adversary may cause severe damage since he can use the sensing data for many illegal purposes ie sabotage blackmail For example competitors may use the data to produce a better product ie safety monitoring sensor application Furthermore by stealing routing information the adversary could introduce his own malicious nodes into the network in an attempt to overhear the entire communication If we consider See Answer
