RID分组密码算法的设计与分析
Design and Analysis of the RID Block Cipher Scheme
【摘要】 为实现特殊系统的保密通信,设计了一种基于SP与Feistel的混合网络的分组加密算法(RIDBCA).利用有限域上的加法、乘法和模加、模乘的混合组合加密数据.并通过分析S-盒的差分均匀性和非线性度这两种非线性准则评估算法的安全性.
【Abstract】 For the sake of secure communication in a specific system, a symmetric block cipher scheme (named RIDBCA) is designed, based on SP and Feistel network. In this scheme, data are encrypted by the combination of addition/multiplication in the finite field and module addition/multiplication. By analyzing differential uniformity and non-linearity of S-box, we also make an assessment of this scheme’advantages on security. s
