由GOST类密码的轮函数生成的群

The group generated by the round functions of a GOST-like cipher

R. Aragona, A. Caranti, M. Sala

摘要:

我们定义了一个GOST的推广密码,并研究了由它的轮函数生成的置换群。我们表明,在最小的假设下的组件的密码,这个组是交替组上的明文空间。我们首先证明这个群是本原群,然后应用本原群的O 'Nan-Scott分类。

英文摘要:

We define a cipher that is an extension of GOST, and study the permutation group generated by its round functions. We show that, under minimal assumptions on the components of the cipher, this group is the alternating group on the plaintext space. This we do by first showing that the group is primitive, and then applying the O'Nan-Scott classification of primitive groups.
