It is obvious that “eI=0” case could be gathered only when “ex=0”(X=Xs) with other words when
synchronization between Receiver – Transmitter realized.
Which basically defines the pre-requirements of communication with chaotic masking as;
1- Transmitter and Receiver circuits should be equivalent.
2- Chaotic Transmitter needs to be utilized as well master for synchronization.
3- The amplitude of Transmitted Data selection should be in line with Chaotic X sign, to secure/mask data
correctly.
By using the simulink model shown as Figure 12. Communication with Chaotic Masking can be investigated for
Rucklidge equations.
Figure-12- Simulink Model of Rucklidge Equations for Communication with Chaotic Masking
The variables of the rucklidge oscillators (Master&Sub) are; K = 2 , L = 6. 7 . Initial Values of rucklidge
oscillators are; Master Sys.(Transmitter) X(0) = 1, Y(0) = 0, Z(0) = 4.
5 , PC-Sub Sys’s (Receiver),
X(0) = 1. 1, Y(0) = 0, Z(0) = 4.
6 . It (Transmitted Data) is a sine wave with 5V amplitude. Time series of
“It”(Transmitted data), “X”(Chaotic Masking Wave) shown at Figure 13, as amplitude of “It“is less then
amplitude of X, “It” could not be easily seen over generated “S”(Transmitted/Masked Data Wave) by 3.rd
parties as shown at Figure 14 which supports the aim of secure communication. Synchronization between Master
and Sub Sys Rucklidge oscillators is being taking place within 10 ms as shown at Figure 15 and Figure 16 which
as well the start point of success at de-masking at receiver side as could be seen at Figure 17 and Figure 18.
