Abstract: In this study we show how a moderate amount of random key stream can be used to generate a lifetime supply of keys for one-time pads. We also show how arbitrarily many parties can correspond using the same random key, without compromising one another's communications. The net effect is to make the unbreakable one-time pad practical for widespread use. Provided also is the practical information that you can use to set up your own one-time pad encryption system. The study further describes subtle refinements that you won’t find in other books or articles.
