Abstract
Sometimes the knowledge that is transferred during the communication in between device node is very much confidential that is required to be secure. Since device nodes are resource unnatural and run on battery, power consumption ought to be low to form it operate for several days. For securing the knowledge varied trigonal key encryption algorithms like RC4, DES, BLOWFISH etc., are used. Our aim during this paper is to use security in device network in such the simplest way that it give confidentiality with authentication victimization Stream cipher modes of operation, so that the energy consumption can minimizes at the device node and the life time of device node can increase.
