Research And Implementation Of The Encryption Algorithm

In the information high speed development today, The widespread use of the Internet, so that people recognize the importance of the network. In this situation, Network security alarm frequently sounded, that the file on your computer like data always be destructed, changed and leaked. Therefore, in the network security, the requirement of people more and more high, mainly reflects in normal communication and as well as private data in the transmission, hope to see its content only each other. Data encryption can meet the requirements, and the algorithm has become more and more mature.DES algorithm and RSA algorithms are two typical encryption algorithm. This paper mainly through the principle of two algorithms are analyzed and studied, according to DES algorithm encryption of large quantities of data the advantages of high efficiency, the improvement of the tail debris, according to the RSA encryption algorithm is not easy to be cracked, key encryption keys to use.The program framework is designed on the VISUAL C + + 6.0 platform, the platform has a high efficiency and availability, And using MFC view framework encapsulation together to form a comprehensive encryption system, It can effectively to data encryption, and high efficiency. Realized the sender and the receiving end data encryption transmission, easy operation, and the system reliability is stronger...
