Introduction:
- Cryptography is the art of secure communication, and ciphers are the tools used to achieve it.
- The Beaufort Cipher is a polyalphabetic substitution cipher that was invented in the 19th century.
- It is still used today in certain applications where security is important.
- This article will provide a comprehensive guide to the Beaufort Cipher, including its key features, encryption and decryption process, and use cases.
Key Features of the Beaufort Cipher:
- The Beaufort Cipher is a polyalphabetic substitution cipher that uses multiple alphabets for encryption and decryption.
- It is a symmetric key cipher, meaning the same key is used for both encryption and decryption.
- The Beaufort Cipher uses a tabula recta, which is a grid of alphabets used for substitution.
- The Beaufort Cipher is more secure than a simple substitution cipher because it uses multiple alphabets, making it harder to crack.
