Chapter 2 Question
The “onetime pad” cipher which is attributed to Joseph Mauborgne, is perhaps one of the most secure forms of cryptography. If a security company you worked for wanted to use this and was asking for your opinion what would you say?
Solution
 the onetime pad is a type of encryption which has been proven to be impossible to crack if used correctly.
 Each character from the plaintext is encrypted by a modular addition with a character from a secret random key (or pad) of the same length as the plaintex
 Problems:

 Key must be as big as the message
 Key must be TRULY random (not pseudo random)
 Key is useful only once
 Key must be distributed
