Energy efficient sensor network security using Stream cipher mode of operation

Sometimes the information, which is transferred during the communication in between sensor node, is very much confidential which is needed to be secure. Since sensor nodes are resource constrained and run on battery, energy consumption should be low to make it operate for many days. For securing the information various symmetric key encryption algorithms like DES, BLOWFISH, RC4 etc., are used. Our aim in this paper is to apply security in sensor network in such a way that it provide confidentiality with authentication using Stream cipher modes of operation, so that the energy consumption will minimizes at the sensor node and the life time of sensor node will increase.
