Abstract

Veri güvenliği iletişim sistemleri için çok önemlidir. Güvenliği sağlamak için şifreleme yöntemleri sıklıkla kullanılmaktadır. Kaotik osilatörler, kendilerini tekrar etmeyen sinyaller ürettikleri için verilerin şifrelenmesi için kullanılır. Şifreleme ve şifre çözme işlemlerinin sağlıklı bir şekilde yapılabilmesi için aynı kaotik osilatörler kullanılmalı ve birbirleri ile senkronize edilmelidir. Bu çalışmada, iki kaotik osilatör arasındaki senkronizasyonu gerçekleştirmek için frekans bölmeli çoğullama (FBÇ) yöntemi kullanılarak şifrelenmiş veri ve senkronizasyon sinyali alıcı tarafına iletilmiştir. Verici tarafında şifrelenecek sinyalin şifreleme kalitesini artırmak için yüksek frekanslı anahtarlama kullanılır. Oransal-İntegral-Türevsel (OIT) kontrol, iki kaotik osilatör arasında senkronizasyon sağlamak için kullanılır. Orijinal sinyal ile şifre çözme sinyali arasındaki doğruluk ilişkisini belirlemek için korelasyon testi, tepe sinyali gürültü oranı (TSGO), ortalama kare hatası (OKH) ve spektral entropi kullanıldı. Sonuç olarak oluşturulan sistemin şifreleme başarısı ve güvenilirliği simülasyon programları ve sayısal analizler ile doğrulanmıştır.

Transmitting the Chaotic Masked Audio Signal from a Single Channel

Abstract

Data security is very crucial for communication systems. Encryption methods are frequently used to ensure security. Chaotic oscillators are used for the 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 healthily. In this study, the encrypted data and synchronization signal are transmitted to the receiver side using the frequency division multiplexing (FDM) 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. Proportional-Integral-Derivative (PID) control is used to provide synchronization between two chaotic oscillators. The 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, simulation programs and numerical analysis verified the encryption success and reliability of the created system.
