Techniques to strengthen one-time pad encryption
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.
1. A computer-implemented method for strengthening an OTP (one-time pad) encryption system, said method comprising the steps of:
encrypting plaintext with a one-dimensional OTP key in an XOR operation to produce ciphertext; and
obfuscating the ciphertext with a one-dimensional AutoKey in an XOR operation to produce AutoKeyed ciphertext; wherein:
the OTP key is generated by a truly random number generator;
the AutoKey is a reusable key; and
the AutoKey is uniquely linked to a KernelKey via a field within a header of the KernelKey, wherein the KernelKey is a reusable key, and the field contains the first j bytes of the AutoKey, where j is a positive integer;
said method further comprising the step of obfuscating byproducts of the OTP encryption with the KernelKey;
wherein the byproducts comprise items from the group of items consisting of:
bin files storing user preferences; and
log files containing information as to a purpose of the OTP encryption.
