Explain how to perform the Vernam cipher encryption operation.
What will be an ideal response?
To perform the Vernam cipher encryption operation, the pad values are added to numeric values that represent the plaintext that needs to be encrypted. Each character of the plaintext is turned into a number, and a pad value for that position is added to it. The resulting sum for that character is then converted back to a ciphertext character for transmission. If the sum of the two values exceeds 26, then 26 is subtracted from the total. The process of keeping a computed number within a specific range is a key concept in modular arithmetic.
