BLOKZİNCİRİ TABANLI SİBER GÜVENLİK SİSTEMLERİ

Kripto paralar (cryptocurrency), eşler arası (Peer-to-Peer) mimaride birbirine bağlı madenci düğümü adı verilen bilgisayarlara ve blokzinciri yapısında tutulan kayıt sistemine dayanmaktadır. Bu sistemler sadece bir para birimi sağlamamakta, bu altyapılar üzerinde çeşitli 'merkezi olmayan' (decentralized), dağıtık (distributed) sistemler/yazılımlar tasarlanmaktadır. Bu çalışmada blokzinciri sisteminin nasıl çalıştığı, sağladığı veri bütünlüğü, kullanılabilirlik, mahremiyet gibi güvenlik servisleri ve hata toleransı incelenmektedir. Blokzinciri yapısının; nesnelerin interneti (Internet of Things), akıllı şehirler, kişisel verilerin korunması, bilgisayar ağları için kullanımı gibi siber güvenlik konularındaki çalışmalar ele alınmaktadır. Blokzinciri uygulamalarındaki temel sorunlara ve olası çözümler gözden geçirilmiştir. Bu tür çözümlerin ağ güvenliğinde kullanımına dair önerilere yer verilmiştir.
