| Abstract: | By analyzing the principles and application of the encrypted data,the paper describes a way of randomicity quantitativeness techniques on the data encrypted based on the normal distribution and chi-square distribution.Taking existing MatLab function erfc and chi2cdf into account,the paper calculates the statistics of data encrypted and draws the maps using the statistics.It also makes a analysis of randomicity quantitativeness on the different ciphertext which comes from different symmetric encryption algor... |
