What will be the plain text corresponding to ciphered text “BKC” i

1.	What will be the plain text corresponding to ciphered text “BKC” if the bifid cipher is used for encryption with key as “KEY” and period 5?(a) MSD(b) SRT(c) KVK(d) VVSI got this question in final exam.This question is from Cryptography in portion Cryptography of Data Structures & Algorithms II
Answer» The CORRECT option is (c) KVK Easiest explanation - The decryption in bifid cipher begins IDENTICALLY to encryption. Then we find the corresponding coordinates and then we get the plain text. So the plain text is “KVK”.
