Enhanced secure data transfer for WSN using chaotic-based encryption

Abstract

Processes on Wireless Sensor Networks (WSN) and their areas of use have become more widespread, and the issue of net-work security has appeared as one of the primary necessities. As power of the processor, memory and energy sources are limited on wireless sensor network nodes, traditional encryption structures are not found effective. With these criteria taken into consideration, the need for less process load and energy consumption as well as a powerful encryption is obvious. In this study, a chaotic encryption system to meet the security need on WSN using chaotic systems was carried out. The chaotic system developed here and the commonly used Skipjack encryption were compared with the help of algorithm OPNET Modeller software and better results were achieved.
