Coding method using genuine random sequences

摘要

For encoding a binary plain text, a genuine random sequence is used, and the same is transmitted to the receiver along with the secret text as a concealed part of the latter, encoded using a secret code S. With the aid of the secret code S, which is the same for the sender and the receiver, it can be recovered at the receiver, enabling the latter to determine the plain text. The code S can be altered for each new secret text sequence by means of the previously transmitted random sequence.
