Suppose a plaintext message x is encrypted using the Caesar cipher b = a +26 10 where each letter of the alphabet is assigned a numerical value (A = 0, B = 1, C = 2, ..., Z = 25), the variable a represents the numerical value of a letter in x, and b represents the numerical value of the corresponding letter in the ciphertext message y. If y = WKDR SC MYYV, then decrypt y to obtain the plaintext message x. Enter the decryption of each letter of y in the boxes below.

Use symmetric ciphers to encrypt message "“promise" and decrypt message "FOG". The representation of characters in modulo 26 is described as follows: Plaintext - a bcdefg|hijk1 mnopar stuvwx y z Ciphertext A BCD|EFG|HIJKL|M|NO|P|Q|R s T|U|VwxY|Z Value 00 01 02|03 04 05 06|07|08|09|10|11 12|13|14|15 16|17 18|19 20 21 22 23 24 25 The mathematical equations for encryption and decryption can be described as follows: Encryption Ea:i→i+kmod 26 Decryption Da : i→i-k mod 26 i represents the messages (plaintext or cipher), k represents a symmetric key. In this case k=20
