Description: Digital Images and video encryption plays an important role in today’s multimedia world. Many encryption
schemes have been proposed to provide security for digital images. Usually the symmetric key ciphering algorithms
are used in encrypting digital images because it is fast and use the techniques for block and stream ciphers. Data
Encryption Standard is symmetric key encryption algorithm. In spite of the successful cracking of the data
encryption standard by massive brute force attacks, data encryption standard algorithm is an entrenched
technology and still useful for many purposes. In this paper, we use some of the image quality encryption
measuring factors to study the effect of data encryption standard algorithm in image ciphering. The results show
that the data encryption standard algorithm is fast and it achieves a good encryption rate for image ciphering using
different modes of operation.

Description: DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。虽然56位密钥的DES算法已经风光不在,而且常有用Des加密的明文被破译的报道,但是了解一下昔日美国的标准加密算法总是有益的,而且目前DES算法得到了广泛的应用,在某些场合,她仍然发挥着余热.（如：UNIX的密码算法就是以DES算法为基础的）。将其修改为三重DES也能抵抗破解。-DES (Data Encryption Standard) algorithm, in 1977 the U.S. government s official permission, is a 56-bit key to encrypt 64 data. 56 keys of the DES algorithm scenery is not, and often with Des encryption expressly decipher reported, but look at the old standard encryption algorithm is always useful, but the DES algorithm has been widely used in a some occasions, she still plays a waste heat. (such as: UNIX password algorithm is DES algorithm-based). To modify the Triple DES is also resistant to cracking.
