Tarama Modeli Kullanan Karma Bir Görüntü Şifreleme Yöntemi

Bu çalışmada, görüntü şifrelenmesi için kullanılabilecek geleneksel kripto sistemlerinden oluşan karma bir şifreleme yöntemi önerilmiş ve bu yöntem uygulama ile anlatılmıştır. İnternetin yaygın olarak kullanılması ve paylaşılanlara 3. Şahısların erişebiliyor olma durumu ve düşüncesi metin ve görsellerin şifrelenerek dijital ortamda gönderilmesi zorunluluğunu doğurmuştur. Geleneksel kripto sistemler metin şifrelemede kullanılmasına rağmen, görüntü şifrelenmesinde yüksek korelasyon ve veri miktarından dolayı tercih edilmediği görülmüştür. Kriptoloji ile ilgili genel bilgi verildikten sonra bazı güncel görüntü şifreleme algoritmalarına ve bu algoritmaların özelliklerine değinilmiştir. Geleneksel kripto sistemlerinden Sezar, Afin, Vigenere ve Yer değiştirme yöntemleri görüntü üzerindeki piksel renk değerleri ve piksel konumlarına ayrı ayrı uygulanarak şifreleme performansları incelenmiştir. Afin ve yer değiştirme kripto sisteminin beraber kullanılarak yapıldığı bir şifreleme yöntemi önerilmiştir. Şifrelenen görüntü daha sonra 8’e 4 kod ve zikzak tarama modeli kullanılarak kuvvetlendirilmiştir. Performans analizleriyle önerilen yöntem değerlendirilmiştir.

Anahtar Kelimeler:

Şifeleme, renkli görüntü şifreleme, afin şifreleme, zikzak tarama modeli, veri güvenliği

A Hybrid Color Image Encryption Method Using A Scan Pattern

In this study, a hybrid encryption method consisting of traditional crypto systems that can be used for image encryption has been proposed and this method has been described by application. The fact that the internet is widely used and third parties can access what is shared has led to the need for text and images to be encrypted and sent digitally. Although traditional crypto systems are used in text encryption, it has been found that image encryption is not preferred due to high correlation and the amount of data. After giving general information about cryptology, some current image encryption algorithms and the properties of these algorithms have been mentioned. The traditional crypto systems such as Caesar, Affine, Vigenere and Substitution methods have been applied separately to pixel color values and pixel positions on the image, and encryption performance has been studied. A method of encryption has been proposed, in which Affine and Substitution cipher systems are performed together. Then the encrypted image has been strengthened using by 4 out of-8 codes and a zigzag scan pattern. The proposed method has been evaluated with performance analyses.
