Abstract (Tur.)
Geleneksel finansal sistemlerin dijitalleşme sürecinde Merkez Bankası Dijital Paraları (CBDC),finansal kapsayıcılık ve işlem hızı açısından kritik bir rol oynamaktadır. Ancak, blokzincir üzerinde kurgulananCBDC yapılarında "şeffaflık" ve "kullanıcı mahremiyeti" arasındaki dengeyi kurmak temel bir zorluk teşkiletmektedir. Bu kapsamda CBDC ekosistemlerinde işlemlerin geçerliliğini korurken kullanıcı kimliklerini ve işlemtutarlarını gizli tutmayı sağlayan mahremiyet teknolojileri incelenecektir. Sıfır Bilgi İspatları vekriptografik primitifler kullanılarak oluşturulan bir protokol sunulacaktır.

Title Diffie-Hellman Key Exchange Protocol
Speaker Aybüke Şanlımeşhur

Abstract
The Diffie-Hellman key exchange is a cryptographic protocol developed in 1976 by Whitfield Diffie and Martin Hellman that enables two parties with no prior relationship to establish a shared secret key over an insecure communication channel. Its security rests on an asymmetry in computational difficulty: while modular exponentiation over large prime numbers is straightforward to compute, its inverse, the discrete logarithm problem, remains computationally intractable. Nevertheless, advances in computing power and cryptanalysis have exposed limitations in the original protocol, driving the need for meaningful improvements. This study examines the Diffie-Hellman key exchange from a technical perspective, exploring both its mathematical foundations and the principal attack vectors it faces.
