发布时间：2018-08-12 10:42
【摘要】：3D密码是CANS 2008提出的新的分组密码算法,其设计思想是基于美国高级加密标准AES,但3D密码算法采用的是3维结构。该文根据3D算法的结构特点,构造出一类新的6轮不可能差分区分器,将3D密码的不可能差分攻击扩展到11轮。将10轮不可能差分攻击时间复杂度降为318.82。该文中大量应用预计算技术,大大降低了时间复杂度,对于分组密码的实际攻击中的数据处理,提高运算效率过程,有很好的借鉴意义。
[Abstract]:3D cipher is a new block cipher algorithm proposed by CANS 2008. Its design idea is based on the American advanced encryption standard AESs, but the 3D cipher algorithm adopts 3D structure. According to the structural characteristics of 3D algorithm, a new 6-round impossible-differential discriminator is constructed, which extends the impossibility differential attack of 3D cipher to 11 rounds. The time complexity of 10 impossibility differential attacks is reduced to 318.82. In this paper, a large number of pre-computing techniques are applied, which greatly reduce the time complexity, and have a good reference significance for the data processing in the actual attack of block cipher, and for improving the operation efficiency process.
