The Design Of S-Box Based On Cascaded Integer Chaos Applied To Wireless Sensor Network
INTERNATIONAL JOURNAL OF FUTURE GENERATION COMMUNICATION AND NETWORKING(2016)
摘要
In 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 singlelevel 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.
