PATENT DESCRIPTION
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a stream cryptographic method and apparatus therefor. More particularly, the invention relates to a diffusion mechanism for running stream cryptography bit by bit; other than the prior art with a fixed polynomial and Shift operations, the diffusion mechanism is combined flexibly with a variable series of diffusion functions embedded within a diffusion-medium control. 
     2. Description of the Related Art 
     The Applicant&#39;s following patent application is related to the invention and is incorporated herein by reference: “A Cryptographic Method of Multilayer Diffusion in Multidimension”, application Ser. No. 12/726,833, filed Mar. 18, 2010; the prior invention described a diffusion function for one position AF(p 1 , p 2 , . . . , p n ), notated herein as AF(i 1 , i 2 , . . . , i m )=A⊕Ad 1i ⊕A 2i ⊕ . . . ⊕Ad mi ⊕S, the encryption/decryption is completed through a diffusion-cycle T, wherein T=2 U+1 , U=┌log 2 u┐, u=max(d 1 , d 2 , . . . , d m ), based on the dimensional magnitude. 
     The present invention emphasizes multiple diffusion functions at a series of pre-arranged positions to maximize the diffusion cycle. Other than the prior invention for one position, the notation AF(p 1 , p 2 , . . . p k ) herein is for a series of pre-arranged positions; further, it may be described more delicately as or precisely by A performs the diffusion functions F(p 1 , p 2 , . . . p k ). 
     SUMMARY OF THE INVENTION 
     The present invention applies with a diffused mechanism, as such, a variable series of diffusion functions embedded within a diffusion-medium, to generate a maximum diffusion-cycle and nonlinear complexity; additionally, it performs in a serial process for simple design, further, in a parallel process for saving time, or even in a hardware architecture, to gain greater acceleration. Under the combination of diffusion functions, the output bits, with a wide and flexible random distribution, are thus hardly attacked during the long diffusion-cycle; the steps are shown as follows:
         (a) selecting a diffusion mechanism, a diffusion-area, and a diffusion-medium;   (b) setting an initial value of the diffusion-area by an input password;   (c) running the diffusion mechanism to obtain a new value for the diffusion-area;   (d) inputting a bit of a plaintext/ciphertext stream in sequence;   (e) outputting a bit of the ciphertext/plaintext stream, equally, XORing (exclusive-or (XOR) operation) the bit of the plaintext/ciphertext stream with an assigned bit of the diffusion-area;   (f) going back to Step (c) until the encryption/decryption is complete.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       FIG. 1  shows an embodiment of the present invention in flow chart diagram form, comprising steps of: selecting a diffusion-area A, a diffusion-medium S, and a diffusion mechanism F t     1      100 ; initializing A by an input password  200 ; performing F t     1    to obtain a new value of A  300 ; inputting a plaintext in encryption or a ciphertext for decryption, bit by bit  400 ; XORing a plaintext bit in encryption or a ciphertext bit in decryption with a certain bit of A for stream output  500 ; continuing until completing the plaintext in encryption, or the ciphertext in decryption  600 . 
     Moreover,  FIG. 2 , i.e.  FIG. 1 ,  200 , shows an initialization of the diffusion-area by an input password, comprising steps of: inputting the password, bit by bit  210 ; setting the password bit whether controlling over S  220 , if yes, then performing F t     1    whether adding S by the value (0 or 1) of the password bit, to obtain a new value of A  240 , otherwise, writing the password bit directly to A  230 ; continuing until completing the password  250 . 
     Serial Process in Detail: 
       FIG. 1 ,  300 , obtaining a new value A t     1     ×t     2   =A t     1     ×(t     2     −1) F t     1    by a serial process, it would implement a number of diffusion functions F(p 1 , p 2 , . . . , p k ), provided with a simple design but rather time consuming. Furthermore, for the initialization of A,  FIG. 2 , a password bit selects a first value for AF(p)=A⊕Ad 1i ⊕Ad 2i ⊕ . . . ⊕Ad mi ⊕S, and a second value for AF(p)=A⊕Ad 1i ⊕Ad 2i ⊕ . . . ⊕Ad mi . The cryptographic process flow comprises steps of:
         1. choosing a diffusion-area A, with a diffusion mechanism F t     1   ;   2. setting A&#39;s initial value A 0  by a password; t 2 =1;   3. obtaining a new value A t     1     ×t     2   , wherein A t     1     ×t     2   =A t     1     ×(t     2     −1) F t     1   ;   4. inputting a bit of a plaintext/ciphertext stream in sequence;   5. outputting a bit of the ciphertext/plaintext stream, equally, XORing the bit of the plaintext/ciphertext stream with an assigned bit of A t     1     ×t     2   ;   6. letting t 2 =t 2 +1, going back to Step 3, until the encryption/decryption is complete.

     The second value of the diffusion-area A 1×2 =[0110100110110010]; then, another encrypted bit is generated. Accordingly, a diffusion-cycle of F 1 , implying A 1×t     2   =A 1 , requires 2 16 −1 times; thus, running the diffusion mechanism consecutively through the diffusion-cycle, the encrypted data complies with a random distribution thereby avoiding successful crypto-attack; assume a plaintext stream=0, four segments (64 bits) of the random output are appended as below, as samples: 
     Four Segments: (t 2 =1 to 64) 
     1011011100111011 (t 2 =1 to 16), 0000100100010111 (t 2 =17 to 32), 
     0100000011010100 (t 2 =33 to 48), 1011011111111110 (t 2 =49 to 64). 
     Preferred Embodiment II: a 1×16 Diffusion-Area A, a Diffusion Mechanism F 2 . 
     According to a diffusion mechanism arranged with the same positions in sequence, but at different times, the output is sampled out at every corresponding time. Suppose that F 2 =F(13 2 :13) A 0 =[0000000000000000] and S=1 is placed at the anchor-position, the encrypting value A 2×1  thus is obtained from A 2×0 F 2  at the first time, t 2 =1, see A 2  of Embodiment I, short for A 2×1 . The next value A 2×2 , notated as A 4  for short, is thus obtained by running the diffusion functions of the value A 3 ; the steps are also listed as below to let any skilled person gain more understanding: (A 3 =[1000010001101011])
     A 3 F(p)=A 3 ⊕A 3 y p ⊕S;   A 3 F(13)=[1000010001101011]⊕[0000100011010101]⊕[0000000000001000];   A 3 F(13:14)=[1000110010110110]⊕[0001100101101011]⊕[0000000000000100];   A 3 F(13:15)=[1001010111011001]⊕[0010101110110000]⊕[0000000000000010];   A 3 F(13:16)=[1011111001101011]⊕[0111110011010110]⊕[0000000000000001];   A 3 F(13:1)=[1100001010111100]⊕[0110000101011110]⊕[1000000000000000];   A 3 F(13:2)=[0010001111100010]⊕[0001000111110001]⊕[0100000000000000];   A 3 F(13:3)=[0111001000010011]⊕[1101100100001001]⊕[0010000000000000];   A 3 F(13:4)=[1000101100011010]⊕[0000010110001101]⊕[0001000000000000];   A 3 F(13:5)=[1001111010010111]⊕[0011011101001011]⊕[0000100000000000];   A 3 F(13:6)=[1010000111011100]⊕[0100000011101110]⊕[0000010000000000];   A 3 F(13:7)=[1110010100110010]⊕[1100100010011001]⊕[0000001000000000];   A 3 F(13:8)=[0010111110101011]⊕[0101111011010101]⊕[0000000100000000];   A 3 F(13:9)=[0111000001111110]⊕[1110000000111111]⊕[0000000010000000];   A 3 F(13:10)=[1001000011000001]⊕[0010000110100000]⊕[0000000001000000];   A 3 F(13:11)=[1011000100100001]⊕[0110001001010000]⊕[0000000000100000];   A 3 F(13:12)=[1101001101010001]⊕[1010011010101000]⊕[0000000000010000];   A 3 F(13:13)=[0111010111101001]⊕[1110101111010100]⊕[0000000000001000].   

     The new value of the diffusion-area will be A 2×2 =[1001111000110101]. According to the diffusion mechanism using the number of times “2” is a prime number, therefore, the diffusion-cycle still keeps on 2 16 −1 times; thus, also assume a plaintext stream=0, XORing a 16  of A, the output other than Embodiment I is sampled out every two times; with four fragments of the random output appended as below, as samples: 
     Four Segments: (t 2 =1 to 64) 
     0111010100010111 (t 2 =1 to 16), 1000111001111110 (t 2 =17 to 32), 
     1000010100011110 (t 2 =33 to 48), 1101011100000100 (t 2 =49 to 64).

     Provided that F 1 =F(8:8), A 0 =[0000000000000000] and S=1 placed at the anchor-position, the encrypting value A 1×1  is obtained from A 1×0  run by F 1  at the first time, t=1. Now that the diffusion-area is a two-dimension matrix, a position needs to be transformed to the corresponding coordinates (i, j); the details are shown as below (Ax(0), Ay(0) also indicated in boldface hereafter):

     The cryptographic process flow comprises steps of: 
     
         
         
           
             1. choosing a diffusion-area A, creating a diffusion-table F t     1   ; 
             2. choosing a medium-area B, creating a medium-constant BF t     1   ; 
             3. setting A&#39;s initial value A 0  by a password; t 2 =1; 
             4. obtaining a new value A t     1     ×t     2   , wherein A t     1     ×t     2   =A t     1     ×(t     2     −1) F t     1   ⊕BF t     1   ; 
             5. inputting a bit of a plaintext/ciphertext stream in sequence; 
             6. outputting a bit of the ciphertext/plaintext stream, equally, XORing the bit of the plaintext/ciphertext stream with an assigned bit of A t     1     ×t     2   ; 
             7. letting t 2 =t 2 +1, going back to Step 4, until the encryption/decryption is complete.
