Chaos-based encryption and message authentication algorithm for wireless sensor network

Abstract

As for the traditional digital chaos-based scheme being not directly applicable for WSN because some sensor node does not support the float type of computation,integer chaotic maps and its block encryption schemes are firstly in-troduced,and then a novel chaos-based message authentication code (MAC) scheme was proposed,which was length changeable with high-level hybrid chaotic security.At last,a security application solution for data communication on WSN employing the proposed chaos-based schemes is presented,and the performance evaluation on the real-world Mica2 node is analyzed to show that the new security solution is more applicable for WSN than the current most popular security scheme,TinySec.
