What is the key space of an affine cipher?

Friday, 09 August 2024 by Emmanuel Udofia

The key space of an affine cipher is a fundamental concept in the study of classical cryptography, particularly within the domain of modular arithmetic and historical ciphers. Understanding the key space involves comprehending the range of possible keys that can be used within the affine cipher algorithm to encrypt and decrypt messages. The affine cipher

What does Eulers theorem states?

Tuesday, 06 August 2024 by Emmanuel Udofia

Euler's theorem is a fundamental result in number theory, which has significant implications in the field of public-key cryptography. Named after the Swiss mathematician Leonhard Euler, this theorem provides a powerful tool for understanding the properties of integers and their relationships under modular arithmetic. Euler's theorem states that for any two coprime integers and ,

What does Eulers theorem states?

Tuesday, 06 August 2024 by Emmanuel Udofia

Euler's Theorem is a fundamental result in number theory with significant implications in the field of public-key cryptography, particularly in the RSA encryption algorithm. This theorem is named after the Swiss mathematician Leonhard Euler and is closely related to Euler's Totient Function, often denoted as φ(n). Euler's Theorem states that for any integer and that
