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. Platform: |

Description: 加密解密 MFC 程序用DES加密算法编写的加密程序 利用加密程序可以实现对数据信息的加解密功能，数据信息可以是文本、图片、音频、视频文件。
综合实验：建立一加密传输系统，发送方将加密后的密文文件进行传输，发给接收方。接收方将接收到的密文进行解密，并将还原后的明文输出。-MFC program with encryption and decryption DES encryption algorithm the encryption program written using encryption program can be achieved for data encryption and decryption functionality, data can be text, images, audio, video files. Comprehensive experiment: to establish a encrypted transmission system, the sender will be encrypted ciphertext file transfer, distributed to the recipient. The recipient will receive the ciphertext to decrypt, and the restored plaintext output. Platform: |
