| Abstract: | We put forward the definition of a class of special mixcolumn transformation.Properties of branch and counting are researched deeply in this paper.The distribution of branch for the special mixcolumn transformation is researched and the relation between the weight of polynomial c(x) and the branch is given.The enumeration of special mixcolumn transformation is solved.In conclusion,some discussion of the design of block cipher are given and this provides a significant basis for the design and analysis of block cipher. |
