[0057] Table 1 is a statistical table of the change of the initial value of the Logistic mapping with the time-varying factor. It can be seen that when the time-varying factor changes linearly, the generated random initial value changes irregularly and completely random. Under the same other conditions, the Logistic chaotic sequence generated by the initial value can be guaranteed to be completely random, so as to ensure the disorder of the filling method, which is beneficial to the MD5 algorithm to resist dictionary attacks.

[0060] Table 1 Logistic mapping initial value and time factor change result table
[0061] Table 2 and image 3 respectively reflect the change result of the generated key with the time factor. It can be found from the table that when the time factor varies linearly from 70 to 79, the generated key changes irregularly and is completely random; image 3 It reflects the key results generated by changing the time factor in repeate...
