Video Selective Encryption Based on Hadoop Platform The information security technology is one of the key technologies support for the new media of radio and television industry. Video encryption is a computationally intensive and data intensive work. The traditional centralized data encryption system is not enough to cope with the huge amounts of data encryption. It’s capacity also difficult to achieve linear growth of data. Famous for allocation of resources, cloud computing becomes better choice of data processing. In this article AES algorithm is used to encrypt video slice layer. We establish an encryption system of Hadoop cluster based on MapReduce framework, to improve the video encryption speed and optimize video encryption strategies.
