1.	Which of the following is a difference between beaufort cipher and vigenere cipher?(a) they use different tables for encryption(b) vigenere cipher is poly alphabetic whereas beaufort cipher is mono alphabetic(c) vigenere cipher uses a key whereas no key is required for using beaufort cipher(d) they use the same table for encryption, but in a different mannerThe question was asked in a national level competition.My doubt is from Cryptography in chapter Cryptography of Data Structures & Algorithms II
Answer» The correct OPTION is (d) they USE the same table for ENCRYPTION, but in a DIFFERENT manner The best I can explain: Beaufort CIPHER is a variation of vigenere cipher. They use the same table i.e. tabula recta for encryption but the table is used in a different manner.
