Embodiment Construction
[0014] The method randomly distributes the compressed data to the high-dimensional space, compresses and encodes the data in each dimension, merges the high-dimensional data, and encrypts the merged data. In this way, the compression rate can be guaranteed to a certain extent, and the security of the compression algorithm can also be enhanced.
[0015] Taking the distribution of original data into three-dimensional space, the use of static arithmetic coding, and the use of Logistic system to generate pseudo-random numbers as examples, the implementation steps of the algorithm are explained in detail. The algorithm needs to input the data to be compressed and the key k 0 、k 1 .
[0016] Step 1 reads the data to be compressed and encoded into a one-dimensional array.
[0017] Step 2 uses the Logistic system (x i+1 =μx i (1-x i )), randomly divide the data in the one-dimensional array into three parts, the detailed steps are as follows:
[0018] 1) Read each element a in t...
