ABSTRACT:
An encryption/decryption apparatus that provides at least two masks, each of which is used in logic/mathematic operation with information to be encrypted to preserve confidentiality. The operations include exclusive oring, addition, subtraction. The source of the masks can be any commonly found data, for example, the code of a music CD. In such a manner the sender may tell the receiver in private that the masks are from a particular track on a particular CD, sampled in a particular fashion, using a particular password. The product of the number of elements in each mask need not be greater or equal to the number of elements in the data file being encrypted. Repetition may make the decoding easier for an eavesdropper, but the use of a password character array to control the use and sequencing of each set of encoding mask operations greatly helps in maintaining the confidentiality of the data. The present invention includes use as a one-time-pad and can be implemented on personal computers.
