The Enigma machine is an electromechanical encryption device invented in the early 20th century and extensively used by Nazi Germany during World War II. Due to its complex structure and interchangeable components, it could generate hundreds of billions of combinations and was regarded as the most secure communication tool of its time. However, the Allies deciphered the machine’s logic, significantly altering the course of the war.The Enigma Machine (Enigma Museum)" image-alternate="" image-elem

The RSA algorithm is named after its developers—Ronald Rivest, Adi Shamir, and Leonard Adleman—derived from the initials of their surnames. It was developed in 1977 by these three academics. Belonging to the class of public-key (asymmetric) encryption algorithms, RSA has become one of the foundational components of modern digital security architecture. The algorithm was patented in the United States in 1983, with its protection period expiring in 2000. RSA is widely used both for ensuring data c

Cloud Computing is a computing model that enables the storage of data, documents, software, and applications on a virtual repository hosted on the internet and provides online access to this content. This model features a relatively simple management structure that allows users to share server resources. Cloud technology, which is based on the sharing of software and information from central sources, encompasses all services that facilitate the distribution of shared information across computing

Euclidean algorithm is one of the oldest and most fundamental algorithms in the history of arithmetic, used to compute the greatest common divisor (GCD) of two positive integers. The algorithm derives its name from the Alexandrian mathematician Euclid, and its core principles are based on Propositions 1 and 2 in Book VII of his work Elements.Historical and Theoretical FoundationsIn Euclid’s Elements the algorithm is described as a process for finding a common measure of two magnitudes. In ancien

A prime number is defined as a positive integer that is divisible only by 1 and itself. In other words, no other positive integer can divide a prime number. For this reason, prime numbers serve as fundamental building blocks in the formation of all other numbers.The first ten prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29Properties of Prime NumbersPrime numbers hold a unique position in mathematics.-The smallest prime number is 2, and it is also the only even prime number.-All other prime num

Cryptology is an exciting field of science used to conceal information and encrypt it in a way that only the right people can understand it! 🕵️‍♂️📜 Imagine you write a message, but only your friend can decode it. That’s exactly like a secret agent game!The word literally means “the science of secret information.” Today, our phones, computers, and all online transactions remain secure thanks to this encryption.🧠 Features of CryptologyIt keeps information secret and protected.It involves encryp

The Enigma machine is a specialized typewriter used for writing and decrypting encrypted messages. It was most widely used during World War II by the German military for secure communication. Thanks to this machine, enemies could not easily determine the content of the messages.How Does Enigma Work?The Enigma resembles a typewriter from the outside but contains rotating wheels called rotors. When a user presses a letter, the machine transforms it into a different letter. For example, pressing th

WPA3 (Wi-Fi Protected Access 3) is a wireless network security protocol developed by the Wi-Fi Alliance and announced in 2018. Designed to replace WPA2, WPA3 offers advanced encryption methods, stronger password protection, and additional features that enhance security. It includes different security modes for personal and enterprise networks.History and Development ProcessThe development of WPA3 began after security vulnerabilities and attack vectors in WPA2 became apparent. The emergence of se

A Man-in-the-Middle (MitM) attack is a cyberattack in which a malicious actor secretly intercepts and potentially alters the communication between two parties who believe they are directly communicating with each other. The attacker positions themselves between the victim and the intended destination to eavesdrop, steal sensitive data, inject malicious content, or impersonate one of the parties.HistoryThe concept of interception in communications has existed long before digital networks, dating

Brute force attack is a method used to break an encryption system, password protection, or digital security mechanism by systematically trying all possible combinations. This type of attack does not rely on shortcuts or prior knowledge to guess a password or encryption key; instead, it aims to find the correct result by exhaustively testing every element in the set of possibilities. The method is commonly used against password authentication systems.Operating MechanismBrute force attacks are typ
