Quick parallel generating method for multidimensional pseudo-random sequence with uniform distribution characteristics
A pseudo-random sequence, uniform distribution technology, applied in the field of network, communication and information security, can solve the problem of not fully meeting the design requirements of the cryptographic algorithm, no longer having the uniform distribution characteristics of tent mapping, affecting the calculation speed, etc., to suppress the short cycle Phenomenon, good scalability, the effect of disassociation

example 1
[0135] Example 1: (The plaintext sequence is a text file)
[0136] (1) Plaintext sequence 1: The hardware of computers has undergone revolutionary changes. The gain in the speed and function has been impressive.
[0137] (2) Seed key and key conversion: (represented by hexadecimal number)
[0138] Selected seed key K = 23984A8D FA712345CD239871B9BA7912
[0139] then k 1 = 23984A8D , k 2 =FA712345, k 3 = CD239871, k 4 =B9BA7912 ;
[0140] And then get the extended key =23984A8D =FA712345, = CD239871 = B9BA7912;
[0141] (3) Initial value vector:
[0142] 0x01234567d807a, 0x89abcdef72be5, 0x3210fedc428a2, 0xba9876543956c
[0143] 0x02468acee49b6, 0xfdb975312de92, 0x456789ab983e5, 0xfedcba98c6e00
[0144] (4) Encryption result (ciphertext sequence)
