Abstract:
1. A diffused data encryption/decryption processing method, wherein comprising the steps of: (a) providing a password binary matrix having a size of n by m bits therein and having w bits belonging to a first binary type; (b) collecting said w bits from said password binary matrix in a predetermined order sequence from k=1 to k=w for diffusion, every point P (c) providing a plaintext binary matrix A having a size of n by m bits therein, therefore said plaintext binary matrix A has a diffusion cycle r and sets a natural number q and 1≦q<r/2; further, the said encryption processing method comprises the steps of: (d) letting k=1; (e) letting t=1; (f) performing one encryption process of single point diffusion from a point P and δ is an XOR logic operator; (g) if t=(r/2)−q, then lets A (h) if k=w then the matrix A
