Özet:

 This study comprehensively examines security and performance-oriented selection and evaluation criteria for Random Number Generators RNGs used in cryptographic applications. The study analyzes the fundamental differences between Pseudo Random Number Generators PRNGs and True Random Number Generators TRNGs. Within the scope of these analyses, entropy sources, statistical characteristics, and performance metrics, as well as their effects on security, are evaluated. The ability of TRNGs to meet high security requirements thanks to their hardware-dependent structures is compared with PRNGs, which offer software-based and low-cost solutions. The study evaluates various criteria ranging from minimum entropy tests to space and energy requirements. It also highlights the fundamental challenges encountered in the design and implementation of RNGs in cryptographic systems. Additionally, the fundamental security requirements encountered in RNG design and how these requirements can be met in practice are discussed in detail. In this context, PRNGs, TRNGs based on physical processes, and hybrid RNG designs are analyzed. The advantages and disadvantages of these different design paradigms are then presented in a comparative manner. In conclusion, this study delivers a framework that unifies security, performance, and design considerations for RNGs, setting a benchmark for future cryptographic research. As a result, this framework forms the foundation for the next generation of secure, efficient, and scalable cryptographic systems.

 Bu çalışma, kriptografik uygulamalarda kullanılan Rastgele Sayı Üreteçleri RSÜ için güvenlik ve performans odaklı seçim ve değerlendirme kriterlerini kapsamlı bir biçimde incelemektedir. Çalışmada, Sözde Rastgele Sayı Üreteçleri SRSÜ ile Gerçek Rastgele Sayı Üreteçleri GRSÜ arasındaki temel farklılıklar detaylı olarak analiz edilmiştir. Bu analizler kapsamında entropi kaynakları, istatistiksel karakteristikler ve performans metrikleri ile bunların güvenlik üzerindeki etkileri değerlendirilmiştir. GRSÜlerin, donanıma bağımlı yapıları sayesinde yüksek güvenlik gereksinimlerini karşılama kapasiteleri; buna karşılık, yazılım tabanlı ve düşük maliyetli çözümler sunan SRSÜler ile karşılaştırmalı olarak ele alınmıştır. Çalışma içerisinde, minimum entropi testlerinden alan ve enerji gereksinimlerine kadar uzanan çeşitli kriterler değerlendirilmiş; kriptografik sistemlerde RSÜ tasarımı ve uygulaması sırasında karşılaşılan temel zorluklara dikkat çekilmiştir. Ayrıca, RSÜ tasarımında karşılaşılan temel güvenlik gereksinimleri ve bu gereksinimlerin pratikte nasıl karşılanabileceği ayrıntılı biçimde tartışılmıştır. Bu kapsamda, SRSÜler, fiziksel süreçlere dayalı GRSÜler ve hibrit RSÜ tasarımları analiz edilerek; bu farklı tasarımların avantajları ve dezavantajları karşılaştırmalı olarak sunulmuştur. Sonuç olarak, bu çalışma RSÜler için güvenlik, performans ve tasarım unsurlarını bir araya getiren bir çerçeve sunarak gelecekteki kriptografik araştırmalar için bir ölçüt oluşturuyor. Böylece, güvenli, verimli ve ölçeklenebilir yeni nesil kriptografik sistemler için bir temel sağlıyor.
