Abstract

A one-time-pad encryption system where encrypted one-time-pad keys can be distributed to users on physical media or on a computer network from a central server. Each one-time-pad key has a key identification number that facilitates key management. Each encrypted data set includes a header specifying an offset within the one-time-pad key for commencement of decryption so that messages can be decrypted in any order. Before encryption begins, the length of remaining unused key is compared to the length of the data set to be encrypted. For ease of transcription or transmission by humans, the encrypted data can be represented as a subset of the 48 keys that are easy to use on a keyboard, preferably the 26 capital letters of the Western alphabet or these letters plus six numerals for a total of 32 characters. A one-time-pad key which is specialized to achieve such encryption can also be used for binary encryption. Encryption control buttons are added to a word processor and other programs as an addition to the user interface.
