ABSTRACT:
The present invention is a real time digital encryption system which may be implemented in either hardware or software. The encryption system uses keys and an algorithm in which the encryption is determined in part by the data being encrypted, to obtain a scramble which is uniquely determined by the combination of the encryption keys and the data being encrypted, thereby making any effort at cryptanalysis extremely difficult, if not impossible. Consequently, anyone seeking to decrypt the data encrypted by the present invention would have to resort to an extensive brute force approach to such decryption efforts.
