Abstract
Disclosed are an encryption method and system. The method comprises the steps of providing a message to be encrypted, said message having a string of characters; and providing a matrix having characters in a last row and numbers in all other rows. A string of numbers is formed from said string of characters by selecting the number in the next to last row in said matrix in the column corresponding to a character of said string of characters. The remaining numbers in said column are shifted down one row, and the selected number is placed in a queue. The method comprises the further steps of continuing until upon depletion of numbers from a column, shifting columns in said matrix, refilling the empty column with numbers from said queue, and shifting each row in said matrix.
