Publication number: 20140177826Abstract: Apparati, methods, and computer-readable media for strengthening a one-time pad encryption system. A method embodiment of the present invention comprises the steps of encrypting plaintext (1) with an OTP key (2) in an XOR operation to produce ciphertext (3); and obfuscating the ciphertext (3) with an AutoKey (4) in an XOR operation to produce AutoKeyed ciphertext (5), wherein the AutoKey (4) is a reusable key.Type: ApplicationFiled: January 20, 2014Publication date: June 26, 2014Applicant: Vadium Technology, Inc.Inventor: Zsolt Ari

Patent number: 7317799Abstract: Methods, computer-readable media, and apparati for securely distributing a cryptographic key (C) from a first party(s) to a second party(s). A method embodiment of the present invention comprises the steps of combining (steps 1 and 2) the cryptographic key (C) with a transport key (T) to form a key set; encrypting (step 7) the key set to form an encrypted key set; distributing (step 8) the encrypted key set across a medium (3); and decrypting (step 9) the encrypted key set to reconstitute the cryptographic key (C) and the transport key (T).Type: GrantFiled: July 18, 2003Date of Patent: January 8, 2008Assignee: Vadium Technology, Inc.Inventors: Wolfgang S. Hammersmith, Lance R. Gaines, Rod G. Nicholls, Byron T. Shank

Publication number: 20030026429Abstract: 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.Type: ApplicationFiled: September 24, 2002Publication date: February 6, 2003Applicant: Vadium Technology, Inc.Inventor: Wolfgang Hammersmith
