Double Bytes Discrete Digital Chaotic Sequence Generator Chip Core

In order to improve security integration of wireless sensor network nodes,the chip core of chaotic serial producer in two bytes for wireless sensor networks security was researched.The period values of different sequences from different initial values in double bytes were gotten through discrete digital chaos calculation.The longer period sequence was obtained by exclusive OR operation through three discrete digital chaos sequences generated from initial values in different groups with different periods.The digital chaos generator chip core was completed,and the symbol of chip core was given.The chip core was simulated.The result provides possibility for security integration in wireless sensor network node.
