METHOD OF GENERATING RANDOM PERMUTATIONS, RANDOM PERMUTATION GENERATING DEVICE, AND ENCRYPTION/DECRYPTION DEVICE HAVING THE SAME

摘要

PURPOSE: the production method of random alignment, the process units and ciphering and deciphering device of random alignment be by simple structure multiplexer and conducting wire connection. ;CONSTITUTION: random alignment generation device (400) includes displacement input unit (410), the first matrix deformation unit (340), the second matrix deformation unit (360) and displacement output unit (460). It includes that N number is digital that displacement input unit, which is entered an initial permutation, these numbers are two or higher, and matrix is arranged in they. The random deformation unit of first matrix execute it is a kind of based at least one random number every row matrix generate the first modified matrix. The random deformation unit of second matrix execute it is a kind of based at least one random number matrix each column, to generate the second modified matrix. The arrangement number outputting unit exports the second modified matrix and generates final arrangement according to row and column. ;The 2013 of copyright KIPO submissions
