摘要：n the block cryptogram algorithm of wireless sensor network, the emphasis is how to design a secure and efficient S-box. A design method of S-box is proposed based on dynamic iteration of the cascaded integer chaos, which is obtained by the cascade and integer quantization of one-dimensional discrete chaotic map logistic and tent. the S-box not only conform to the application requirements of node operation and computational efficiency, but also compensate the degradation of dynamic characteristics of the single-level integer chaos. The performance tests of S-box were carried out, including nonlinearity degree, differential uniformity, strict avalanche criterion, out-put bit independence criterion and bijective property. In contrast to the existing classical S-box based on chaotic map, the results indicate that the S-box has more excellent cryptographic properties, and it can be used as a candidate nonlinear component in the design of block cryptogram algorithm for wireless sensor network.
