Cryptanalysis of Vigenère Cipher: Method Implementation

摘要

Cryptanalysis is the technique of analysing and breaking an encrypted text (ciphertext) to obtain the clear text (plaintext). Cryptanalysis analyses all the information available about the examined methods. This information may be public, originate from plausible assumptions or be able to specifically learn. The type of information available is divided into different attack scenarios to qualify the relevance of the attack or comment on security. In this paper, we will provide an implementation of cryptanalysis methods by cryptanalysing ciphertexts by using Vigenère cipher. The paper shows how the algorithms remain simple enough to implement the message without errors. This paper will allow researchers to better understand the technique's use of mathematical formulas to analyse secure information systems to detect vulnerabilities and shrouded components.
