Abstract

A hybrid one time pad encryption and decryption apparatus with methods for encrypting and decrypting data wherein a one time random number pad provides high security encryption. The random number sequence is encrypted using DES, RSA or other technique and embedded in the message as a function of the random pad itself. This generates an encryption message that is impervious to attempts to directly decode the message text as the message is randomly dispersed throughout a message and the message contains as much quasi-random data as text. The message is also relatively impervious to attempts to decode the cipher, as the cipher is randomly interrupted by the encrypted data.
