ABSTRACT:
A system (100) and method (400, 500) for data encryption and decryption are disclosed. The encryption system is operable at encryption rates in excess of 10 Mbps and is expandable to over 200 Mpbs. For encryption, plain characters are received, and a key block (120) includes key characters corresponding to the plain characters is accessed. A current key character corresponding to a current plain character is located. A next key character corresponding to a next plain character is located. An offset between the current key character and the next key character is determined to encrypt the plain characters. Aliases are used to facilitate the encryption and decryption. Vector distances of offsets are utilized for the encryption and decryption, using many variables and many dimensions, such as using coordinates.
