In the block encryption algorithm of wireless sensor network, the chaotic map is used as a key generator conform to the application requirements of security and efficiency. Due to the one-dimensional discrete chaotic map would appear the degradation of dynamic characteristics after integer quantization, the cascaded and disturbed integer chaotic key generator were constructed in view of the ideas of cascade and disturbance. The performances of dynamic characteristics and statistical randomness were simulated and analyzed for the cascaded and disturbed integer chaotic sequences, and the disturbed integer chaotic sequence whose disturbance position for 1-8 bits was proved to be more excellent, and it can not only meet the encryption requirements of wireless sensor network, but also reduce the computing power and hardware resources overhead of the processor.
