Welcome to the Vigenère Cipher Web application! This tool helps you encrypt messages using a keyword. You don't need to be a programmer to use this app. Follow the ...

The Vigènere Cipher is a method of encrypting alphabetic text by using a form of polyalphabetic substitution, which was developed in the 16th century by French cryptographer Blaise de Vigenère. It ...

Introduction: In this lab activity you will use MatLab and write functions to decrypt a message that is encoded with a Vigenere cipher. This lab is available at www ...

Abstract: 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 ...

Abstract: This paper proposes a cipher algorithm of order /spl theta/ using the Vigenere principle. A cipher method with numerical data is used. The cipher depends on the key that is composed by the ...
