Algorithm 1 The generation of chaos-based PRNG

Input: The initial values of system (2).

1:
for $i = 1$ to 4 do
2:
for $r = 27$ to 29 do
3:
Truncate a chaotic sequence $C_{i}$ from the trajectory of $x_{i}$ ;
4:
Convert the floating number $C_{i}$ of $x_{i}$ into a 32-bit binary using the IEEE-754-Standard;
5:
Fetch the last 16th digital number of the obtained binary string;
6:
end for
7:
end for

Output: Four PRNG are generated from of

x_{1}

x_{2}

x_{3}

and

x_{4}
