Geçmişten günümüze şifreleme, pek çok uygulamada kullanılan farklı yöntemleriyle büyük bir evrim geçirmiştir. Güçlü şifreleme algoritmalarının zaman içerisindeki gelişimi, dijital iletişimde güvenliği sağlayan Açık Anahtar Altyapısını oluşturmuştur. Bu altyapının önemli bir bileşeni olan dijital imzalama günümüzde yaygın olarak kullanılmaktadır ve verinin doğruluğunu, bütünlüğünü ve güvenilirliğini önemli ölçüde sağlamaktadır. Bu çalışmada dijital imzalama yöntemlerinin, günümüz siber güvenlik dünyasında, zararlı yazılımların güvenilirliği üzerindeki etkisi değerlendirilmektedir. Zararlı yazılımların etkileri ve sonuçları her geçen gün artmakta olup, yaygın olarak kullanılan e-imza ve dijital sertifikalar da bu etkileri artırabilmektedir. Bu bağlamda çalışma, farklı yöntemlerle oluşturulan örneklere dijital imzalama uygulanarak, zararlı yazılımların güvenilirlik ölçütlerinin karşılaştırmasını içermektedir. Testler sonucunda imzalı olan zararlı uygulamaların imzasız olan zararlı uygulamalara göre daha düşük olasılıkla güvenlik sistemlerine yakalandıkları ölçülmüştür. Özetle araştırma, dijital imzalamanın zararlı yazılımların yayılımını ne ölçüde etkilediğini ortaya koymayı ve siber güvenlik önlemlerinin geliştirilmesine katkı sağlamayı amaçlamaktadır.

Impact of Digital Signing on Malware in Public Key Infrastructure

Öz

From past to present, cryptography has undergone a significant evolution from past to present, with various methods used in many applications. The development of strong encryption algorithms over time has established the Public Key Infrastructure, which ensures security in digital communication. A key component of this infrastructure, digital signing, is widely used today and plays a crucial role in ensuring the accuracy, integrity, and reliability of data. This study evaluates the impact of digital signing methods on the reliability of malware in the context of today's cybersecurity landscape. The effects and consequences of malware are increasing day by day, and commonly used e-signatures and digital certificates may also exacerbate these impacts. In this context, the study includes a comparison of the reliability metrics of malware by applying digital signing to examples created using different methods. Tests have shown that signed malware applications are less likely to be detected by security systems compared to unsigned ones. In summary, this research aims to reveal the extent to which digital signing affects the spread of malware and to contribute to the development of cybersecurity measures.
