In this paper, the authors have introduced a new symmetric key cryptographic method which is based on two ways simultaneous feedback method applied along two dimensions on plain text. The process starts by dividing the plain text into a number of square matrices where the size of the matrix and no of layers are balanced. For example if plain text has 20 characters then the size of the matrix will (3x3) and no of layers will be 2 and 2 additional residual characters. The initial feedback is predetermined. The forward and the backward feedback are applied to each layer (i.e. each square matrix) along two dimensions (i.e. row wise and column wise).
