one-time pad

(wŭn′tīm′)
n.
A key used in private-key cryptography that is the same length as the contents of the message being encrypted, providing unbreakable encryption if the key is perfectly random and used only once.

For this reason, sensitive applications, for example, financial domain, demand perfect security that can only be achieved by one-time pad (OTP) symmetric-key cryptosystems in which the key used for encryption once is never used anymore at any time [1].
One-time pad [16] is a simple and completely unbreakable symmetric cipher, and it has two perfect characteristics: the key is random and has the same length as the message.
Section 2 discusses the quantum shift register and how to generate a matrix code used in the Diffie-Hellman algorithm to match the key between Alice and Bob to be used later in the Hill cipher algorithm [1] and then generate another matrix code used as a one-time pad (OTP).

Vernam's cryptographic system, known also as one-time pad is a type of the encryption method that has been proven to be impossible to crack if used properly (Shannon 1949).
This was called the one-time pad, where every letter was transposed to another letter located a random distance away.
