Homofonik şifrelenmiş türkçe metinler üzerine ataklar

Emerging technologies make the vital operations performing through insecure channels. At this point, transferring private information between parties and authentication of transferred data can only be possible by the use of cryptography.The security of the cryptographic methods should be examined to test for perfection. Therefore, it is always supposed that the cryptographic method is known on cryptographic attacks.In this work, firstly classical encryption methods and vulnerabilities for Turkish language are reviewed. Herein, homophonic cipher comes one step forward in the alternative classical encryption methods because it generates ciphertexts consisting of variable block sizes. This makes well known attacking models invalid. Therefore, a novel attacking model is aimed to develop for Homophonic cipher in Turkish. This model is investigated on a large data source aiming to detect the characteristic features of Turkish language.
