In this paper we have developed a block cipher, wherein the size of the key matrix is 384 bits and the size of the plain text is as large as we choose. The permutation, the interlacing and the iteration introduced in this analysis are found to cause diffusion and confusion efficiently. Hence, the strength of the cipher proves to be remarkable.
