─ Today, wars take place in cyber world rather than heavy weapons. This recent situation is defined as “cyber war”. The most affected countries by cyber wars are those suffering weakness in information security and, accordingly, one of the most important reasons is the failure of sufficient awareness in these countries regarding to cyber wars which stand the most dangerous hazard both in future and even now. Therefore, cyber wars are not considered as a threat by those countries who are lack of enough awareness resulted in ignoring the required measures related to information security. However, the protection of information and providing its security become increasingly more important. For achieving this, one method includes keeping the current information encrypted (i.e. hiding), transmission and sharing in this way, which is called “cryptology”. Cryptology science deals with data encryption and decryption. The aim of this study is to draw attention to the information security in terms of national security against possible cyber wars, to develop a national cryptographic (encryption) algorithm considered to be highly profitable in this area, and produce a confident cryptological algorithm performing a confidence examination against letter frequency analysis. In this study, it has been developed a new and different algorithm and examined its confidence against letter-based analysis, a technique of attack. Thus, we intended to draw attention on the requirement of innovative productions as well as discussing the current ones required for national information security.

Günümüzde savaşlar artık ağır silahlarla değil elektronik ortamlarda gerçekleştirilmektedir.Bu durum siber savaş olarak nitelendirilmektedir.Siber savaşın en etkili olduğu ülkeler bilgi güvenliğinde zaafiyet yaşayan ülkelerdir. Bunun en büyük sebebi gelecekte ve hatta şimdinin de en büyük tehlikesi olan siber savaşla ilgili bu ülkelerde yeterli farkındalık oluşturulamamasıdır.Makaledeki amaç, ülkenin siber savaşlara karşı milli güvenliği hususunda bilgi güvenliğine dikkat çekmek, bu alanda faydalı olacağına inanılan ulusal bir kriptografi algoritması geliştirmek ve geliştirilen algoritmanın harf frekans analizine karşı güvenirlik incelemesini yaparak ulusal bilgi güvenliğinde güvenilir bir şifreleme algoritması üretebilmektir.
