The sensors of wireless sensor networks communicate by sending and receiving packets among one another. It is important to provide security in wireless sensor networks so that only the valid or legitimate user gets the message. Cryptography is an important concept which provides security in wireless sensor networks. It encrypts the data and provides diffusion and confusion to hide the ciphertext’s relationship with the plaintext and the key. An intruder may eavesdrop or sniff on the network to capture the packets, If cryptography is done on the plaintext then even if the intruder gets the packets, it will be extremely difficult for him to understand the message. This will provide confidentiality of the data in wireless sensor networks. In this paper, we have proposed a cryptographic approach to provide privacy preservation or confidentiality in wireless sensor networks. We simulated sensor network in network simulator (ns – 2.35) using AODV protocol. Our proposed approach is implemented in AODV protocol and the performance is compared with other existing approaches. Comparison is done on the basis of security, bit flip rates and occurance avalanche effect.
