Abstract (2. Language): 
Security of valuable multimedia contents such as images in personal photograph albums, electronic publishing, frames of multicast video conference can be achieved by image encryption. Secure transmission of these contents is required to be rapid, efficient and practical. Hence, image encryption process must be chosen not only to satisfy the security goals but also to fulfill these requirements. Due to the inadequacy and inefficiency of conventional text based information encryption methods, researchers have proposed several encryption schemes. Many of them are based on chaotic algorithms. Recently, the studies are concentrated on some weaknesses of chaotic algorithms and most of the presented solutions came up with complex structured chaotic maps. In this paper, we present a self-diagonal shuffler mechanism embedded to one dimensional chaotic encryption system to overcome its leak points while keeping simplicity and efficiency properties.

Abstract (Original Language): 
Kişisel resim albümlerindeki resimler, çoklu video konferanslara ait elektronik yayın kareleri gibi değerli medya içeriklerinin güvenliği resim şifreleme yöntemleri ile sağlanır. Bu içeriklerin güvenli iletimi hızlı, verimli ve pratik olmak zorundadır. Bu nedenle; resim şifreleme teknikleri seçilirken sadece güvenlik değil, aynı zamanda bahsi geçen özellikleri sağlayacak şekilde seçilmelidir. Klasik metin tabanlı bilgi şifreleme yöntemlerinin resim şifrelemedeki yetersizliği ve verimsizliği sebebi ile literatürde bu amaç için önerilmiş şifreleme algoritmaları mevcuttur. Bu şifreleme yöntemlerinin çoğu kaotik algoritmalara dayanır. Son zamanlarda bu konudaki çalışmalar çoğunlukla kaotik algoritmaların zayıflıklarına odaklanmıştır ve beraberinde karmaşık yapıda kaotik haritalar oluşmuştur. Bu çalışmada, basitlik ve verimlilik özelliklerini kaybetmeksizin kaotik şifreleme yöntemlerinin zafiyetlerini ortadan kaldırmaya yönelik tek boyutlu kaotik şifreleme sistemlerinde gerçekleşen bir öz-köşegen kaotik şifreleme algoritması önerilmektedir.
