摘要
针对序列密码算法中非线性布尔函数的实现,利用布尔函数的拆分建模,提出一种以布尔函数拆分、布尔函数计算和输出回写为基础的通用非线性布尔函数处理模型,模型能够完成不同形式的非线性布尔函数实现。为更好地评估模型的实现能力,完成了序列密码中常见的非线性布尔函数的算法适配。适配结果表明,和现有的方式相比,模型适配能力较强,资源占用低,具有较好的发展前景。
Focus on the realization of non line Boolean function of the stream cipher, this paper uses the split and modeling of the Boolean function, and proposes a universal process model of non line Boolean function based on the split of the Boolean function and the calculate and backup as well. in order to evaluate the ability of the model better, this paper finishes the adapt of common stream cipher. The result shows that this model owns good ability of adapt and lower resource ,and then has a good development future.
