发明名称 SYSTEM AND METHOD FOR HIGH SPEED REVERSIBLE DATA ENCRYPTION
摘要 The present invention provides systems and methods for facilitating encryption and decryption of data. In accordance with an exemplary embodiment of the present invention, an encryption is located (201) to provide a located character (209) in the encryption key. The number of characters in the data is determined (217). The position of the located character in the encryption key is shifted by a predetermined amount to determine a shifted position of the located character in the encryption key. Accordingly, the shifted position is located at a position in the encryption key that is the located character shifted by the predetermined amount. A first character in the data is translated with the character located at the shifted position to provide an encrypted character. The shifting and translating are repeated for any remaining characters in the data to provide encrypted data. The encrypted data may be decrypted using the above process, so that the encryption is reversible.
