Reseach of Image Encryption Algorithm Based on S-DES

摘要：

This paper mainly studies one kind of simple image encryption algorithm which can help general users to keep secret from the data information. The algorithm is modified from the DES whose processing may be divided into three steps: initial transform IP, 16 round iterations, and initial inversed transforms IP-1. Initial transformation and inverse transformation can enhance difficulty to be understood for data, and not to affect security of data. Modified encrypted algorithm, namely S-DES, carries on two round iterative encryptions to clear text. The length of block and secret key reduced. Therefore S-DES algorithm is more inexpensive than the DES encryption algorithm and remains many merits of DES.
