Data security is very crucial for communication systems. Encryption methods are frequently
used to ensure the security. Chaotic oscillators are used for encryption of data because they
produce signals that do not repeat themselves. Identical chaotic oscillators should be used
and synchronized with each other in order to perform encryption and decryption processes in
a healthy way. In this study, the encrypted data and synchronization signal are transmitted to
the receiver side using frequency division multiplexing method to realize the
synchronization between two chaotic oscillators. High-frequency keying is used to increase
the encryption quality of the signal to be encrypted on the transmitter side. ProportionalIntegral-Derivative control is used to provide synchronization between two chaotic
oscillators. Correlation test, peak signal to noise ratio (PSNR), mean square error (MSE) and
spectral entropy were used to determine the accuracy relationship between the original signal
and the decryption signal. As a result, the encryption success and reliability of the created
system were verified by simulation programs and numerical analysis
