What is a Vernam cipher?
What will be an ideal response?
Also known as the one-time pad, the Vernam cipher was developed at AT&T and uses a set of characters for encryption operations only one time and then discards it. The values from this one-time pad are added to the block of text, and the resulting sum is converted to text. When the two sets of values are added, if the resulting values exceed 26, then 26 is subtracted from the total (a process called modulo 26). The corresponding results are then converted back to text.
