| 摘 要： | 评估了一类基于混沌函数的分组密码(generalized Feistel structure,简称GFS)抵抗差分密码分析和线性密码分析的能力.如果轮函数是双射且它的最大差分特征概率和线性逼近概率分别是p和q,则r轮GFS的最大差分特征和线性逼近的概率分别以pr-1和qr-1为其上界.

| Abstract: | The security evaluation of a class of block ciphers based on chaotic maps against differential and linear attacks is studied. If the round function is bijective and its maximum differential and linear characteristic probabilities are p and q respectively, the upper bounds of maximum differential and linear characteristic probabilities for r rounds are pr-1and qr-1 respectively. |

| Keywords: | block cipher block cipher based on chaotic maps differential cryptanalysis linear cryptanalysis security evaluation |
