Secure Data Transmission in Wireless Sensor Networks using Paillier Algorithm

sensor nodes are vulnerable to various security threats and resource constraints. A wireless sensor network is very vulnerable because there is no centralized data repository, so data can be stolen by eavesdropping. The nodes in WSN are distributed or arranged in a network for a specific function. Sensors, processor and radio transceiver are the important components an important application of wireless networks. The main goal of the proposed work is to secure the data which is transfer from one node to another node. It uses a secure key to transfer the data. The proposed system uses a paillier algorithm to generate a key to secure the data during transmission.
