“…Residue number system is described as a non-weighted number system having numerous benefits in numerical computations. The inherent features in RNS such as the digit-to-digit computations, parallelism, fault tolerance, high computational speed and low power dissipation make it ideal for implementation in fields of communication [9,10], Digital Signal Processing (DSP) [14,26,32], intensive computations such as digital filtering, correlations, convolutions, direct digital frequency synthesis [6], Discrete Fourier Transform (DFT) computations [24], Fast Fourier Transform (FFT) computations, image processing [1,10,20,25,28] and cryptography [27,33]. RNS are based on the congruence relation.…”

In this paper, we propose an enhanced perceptual video encryption technique to speed-up and secure cipher video transmitted across networks using Residue Number System (RNS). The technique proposes a new reverse converter with smaller dynamic range using the moduli set {2n-1, 2n, 2n+1} that is integrated into our previous work of [2]. After encryption, cipher video is encoded into three residual videos that have smaller pixel values and ideal for transmission across networks. Instead of transmitting the three (3) residual videos, the technique effectively transmits and decodes only two (2) of them back into the original video with same visual quality. Experimental results show that the technique enhances transmission speed and security of cipher video across networks.
