A New Software Implementation of TRIVIUM Stream Cipher

Öz

Security, reliability and robustness against reverse engineering attacks are crucial for a high-quality cryptographic tool. Additionally, speed, efficiency and portability are also key components of such a tool. TRIVIUM has been specified as an International Standard since it is a lightweight yet highly secure stream cipher. However, TRIVIUM is designed to be hardware-oriented and its software implementation still lacks portability for high-level programming languages. In this study, we propose a software implementation of TRIVIUM, which enables us to achieve higher bandwidth and lower machine and programming language dependency, comparing to its original software implementation. Our implementation outperforms the original software implementation of TRIVIUM for widely used programming languages in terms of speed and applicability, which makes it possible to reach broader usage.

TRIVIUM Akış Şifreleyici için Yeni bir Yazılım Uygulaması

Öz

Güvenlik, güvenirlik ve tersine mühendislik saldırılarına karşı gürbüzlük yüksek kaliteli bir şifreleme aracı için vazgeçilmezdir. Ek olarak, hız, verimlilik ve taşınabilirlik de bu tür bir aracın temel bileşenleridir. TRIVIUM hafif fakat yüksek güvenlikli bir akış şifreleyici olduğu için Uluslararası Standard olarak belirlenmiştir. Buna karşın, TRIVIUM donanım temelli olarak tasarlanmıştır ve yazılım temelli uygulaması halen yüksek seviyeli dillere taşınırlıktan yoksundur. Bu çalışmada, TRIVIUM için orijinal yazılım uygulamasına kıyasla daha yüksek bant genişliği ve daha düşük makine ve programlama dili bağımlılığına erişmemizi sağlayacak yazılım temelli bir uygulama önermekteyiz. Uygulamamız geniş kullanıma sahip programlama dillerinde hız ve uygulanabilirlik açısından TRIVIUM’un orijinal uygulamasını aşmakta, bu da onun daha geniş kullanımına olanak sağlamaktadır.
