As indicated, selection of amplitude of It(Transmitted Data) is a pre-requirement of secure Communication with
Chaotic Masking as “It” is going to be masked into X(Chaotic Masking Wave) therefore amplitude of “It”
should preferably be less than amplitude of “X”.
In case the amplitude of “It” is greater than amplitude of “X” S(Transmitted/Masked Data) is mostly consist of
“It” values as shown at Figure 20 therefore unfortunately It could be easily seen by 3.rd parties, Where security
of communication can be increased by selecting smaller amplitude values as an example shown at Figure 19.

4. Conclusions
In this work, we studied secure communication by synchronization and chaotic masking of Rucklidge attractors,
as first step we investigated the nonlinear equations of Rucklidge and its dynamical behavior by using Matlab
