KRİPTOLOJİ VE EN YAYGIN KULLANILAN KRİPTOGRAFİK ALGORİTMALAR Bölüm I: Temel kavramlar, simetrik ve açık anahtarlı algoritmalar, özet fonksiyonları ve performans ölçümleri
Kriptoloji, bilgiyi yetkisiz kişilerden korumak için şifre tasarlayan kriptografi ile bu şifreleri çözmeye çalışan kriptanalizin birlikte oluşturduğu bilim dalıdır. Bir web sayfasını açmak, banka uygulamasına girmek ya da e-imzalı bir dilekçeyi UYAP'a göndermek, arka planda aynı küçük algoritma ailesinin çalışmasına dayanır. İki bölümlük serinin bu ilk makalesi, söz konusu ailenin kendisini ele almaktadır.

TERÖRÜN FİNANSMANI VE KARA PARA AKLAMADA ELEKTRONİK PARA İLE BLOKZİNCİRİN ROLÜ
Terörün finansmanı ile suç gelirlerinin aklanması, yöntem bakımından birbirine yaklaşan ama amaç bakımından ters yönde işleyen iki süreçtir. Aklamada kirli bir kaynağa temiz görünüm kazandırılmaya çalışılır. Terörün finansmanında ise kaynak çoğu zaman yasaldır ve asıl gizlenen şey paranın varış noktasıdır. Son on yılda her iki süreç de bankacılık sisteminin kenarında gelişen iki altyapıya kaymıştır: ön ödemeli kartlar, e-cüzdanlar ve mobil para gibi elektronik para araçları ile blokzincir ...

YAPAY ZEKA VE MESLEKLERİN DÖNÜŞÜMÜ
Üretken yapay zekânın istihdam üzerindeki etkisi, önceki otomasyon dalgalarından bir noktada ayrılır: baskı bu kez el emeğine değil, büro ve bilgi işlerine yönelmiştir. Bu makale önce maruziyet yazınını karşılaştırır. Frey ve Osborne’un (2017) meslek temelli %47’lik tahmini ile Arntz vd.’nin (2016) görev temelli %9’luk tahmini arasındaki fark, ölçüm biriminin meslek mi görev mi olduğuyla açıklanır.

Assessment of Diminished Value in Motor Vehicle Accidents: From Formulaic Calculation to Market-Based Appraisal in Türkiye
A vehicle damaged in a traffic accident sells for less on the second-hand market than an otherwise identical vehicle with no accident record, even where the repair is technically flawless. That gap is termed diminished value and is compensable under Turkish law as a component of pecuniary loss arising from tort. How it should be calculated has been contested in Türkiye since 2015.

Who Is Liable When an AI Agent Commits a Crime? Attribution of Responsibility and Forensic Traceability in Agentic AI
Agentic AI describes systems that combine large language models with tool use, persistent memory and autonomous decision loops to carry out multi-step tasks without human intervention. The capacity of these systems to act directly in the world — deleting files, transferring funds, executing code, exfiltrating data — raises a novel question of responsibility for the legal order.

Forensic Detection of Synthetic Media: Is Deepfake Audio and Video Evidence Still Reliable?
The rapid maturation of generative artificial intelligence has made the production of synthetic audio, images and video (deepfakes) routine. This has undermined the long-held trust in audiovisual records and created an obligation to test technically the authenticity of every multimedia item submitted in a forensic process.

The Forensic Evidentiary Value of End-to-End Encrypted Messaging: WhatsApp, Signal and Telegram
End-to-end encryption (E2EE) has become the standard in messaging applications and, while strengthening privacy, has largely rendered traditional interception ineffective. This has created a paradigm shift for digital forensics: evidence must now be obtained not from the communication channel but from its endpoints — devices and cloud backups.

Cryptocurrency and Blockchain Forensic Tracing: From Wallet to Perpetrator
The pseudonymity offered by crypto assets has made them a preferred instrument for money laundering, ransomware, fraud and sanctions evasion. Conversely, the public and immutable ledger structure of most blockchains creates a forensic traceability absent from traditional financial systems. This article examines the forensic tracing of crypto-asset transactions along three axes.

Applying LoRa and LoRaWAN Technology in Industrial Communication Systems
Industrial Internet of Things (IIoT) applications demand reliable, low-power, long-range wireless communication infrastructure. Developed to overcome the limited range and high energy consumption of conventional wireless technologies (Wi-Fi, Bluetooth, ZigBee), the LoRa modulation technique and the LoRaWAN protocol stack built on it have become the preferred choice in industrial communication in recent years.

Quantum Computers and Encryption — Preparing for Q-Day: From Shor's Algorithm to the NIST Post-Quantum Standards
Quantum computers pose an existential threat to the cryptographic infrastructure of the digital age. The algorithm Peter Shor developed in 1994 theoretically defines quantum circuits able to solve the factoring of large numbers — the mathematical foundation of today's RSA encryption — in polynomial time.

Artificial Intelligence and NLP: Natural Language Processing with Python from the Transformer to RAG Systems
Natural Language Processing (NLP) is one of the fastest-growing subfields of artificial intelligence. The 2017 paper "Attention Is All You Need" and the Transformer architecture created a paradigm shift; BERT (2018), GPT-3 (2020) and the Large Language Models that followed carried NLP from research laboratories into corporate production environments.
