A Study on the Stream Cipher Embedded Magic Square of Random Access Files

Magic square and stream cipher issue are very interest well-tried topic. In this paper, we are proposed a new scheme which stream cipher application for random access file that based on magic square method. By the way, there are two thresholds to secure ours data, if decrypts only by the stream cipher. It isn’t to recovery original source. In other hand, we improve the model of cipher stream to strong the defense efficiently, it also own high speed calculate to most parts of key stream generator.
