Abstract:
As ARM7 processor has limited capability of processing digital videos,this article has proposed a new way to implement the video encryption and decryption system based on ARM7 processor. The way that can encrypt the important information of video very effectively costs little calculation of processor and prevents the attacks from hackers.This implementation is based on the composite algorithem of Knight-tour transform and Arnold transform which can benefit from each other.As Knight-tour transform costs lots of calculations of CPU,this article has found a good way based on LUT(Look-up table)to reduce costs of calculation. The experiment based on ARM7 target has approved that the speed of processing a frame of vedio has been improved up to 30 times with the way from this article for encryption.
