Is the Vigenère Cipher a Transposition Cipher? | SecurityFirstCorp

Is The Vigenere Cipher A Transposition Cipher? Understanding the Vigenere cipher and its classification is essential for anyone interested in the world of cryptography. In this informative video, we will clarify the differences between transposition and substitution ciphers, focusing specifically on the Vigenere cipher. We will begin by defining what transposition ciphers are and how they function, emphasizing the rearrangement of letters without altering their identity.

Next, we will dive into the mechanics of the Vigenere cipher, illustrating how it utilizes a keyword to create a polyalphabetic substitution method. We will explain how the encryption process works, detailing the application of shifts based on the keyword and how this contributes to the cipher's security against frequency analysis.

We will also discuss the implications of this cipher's structure, touching on its strengths and vulnerabilities. By the end of this video, you will have a clearer understanding of why the Vigenere cipher is categorized as a substitution cipher rather than a transposition cipher.
