The invention is related to working with variable diffusion functions on a multidimensional diffusion-area (plaintext/ciphertext); every diffusion function run in a cycle times, wherein repeating one certain times on the plaintext to get a ciphertext, and afterward, repeating the other times on the ciphertext to recover the plaintext, is performed in sequence to complete the encryption and the decryption. According to FIG. 1, the system comprises of: inputting a plaintext in encryption or a ciphertext in decryption 100; reading every password segment in order, forward in encryption or backward in decryption 200; and further, converting the plaintext dimensions by the password segment 300; implementing the diffusion function of Point 410, Block 420 or Frame 430, repeated TE times in encryption, TD times in decryption 400; going back to 200 until completing all password segments 500, and outputting the ciphertext in encryption or the plaintext in decryption 600. |
