针对以上过程存在的弊端,本文提出一种H-R自适应单元网格划分方法,在程序中自动生成新的自适应数据文件,这就节省了大量的前处理和后处理工作;另外,自适应过程的判别采用了一种新的自适应误差分析方法,即以连续误差分析作为局部误差分析和以迭代误差分析作为整体误差分析相结合的误差分析方法,从而大大提高了边界元解的计算精度。

Based on the fundamental principle of differential cryptanalysis and corresponding relation between the iteration of chaotic system and the round of block cipher, two important concepts, namely the iterative differential distribution (IDD) and the differential-invalid exponent (DIE) are proposed, which are used in evaluating chaotic system s power of conteracting the differential cryptanalysis.
