Abstract:

On the basis of our study on block cipher and its operation mode, a novel grow tree composite model was proposed using the theory in orthogonal space. All the classical block cipher algorithms can be composed into a new output sequence with high security and low computation complexity. The experimental result and theoretical analysis show the excellent performance of this model.
