Abstract
Video broadcasting has attained high importance due to the popularization of networks. Video communication has lot of advantages but not limited to e-learning, surveillance, etc. Video encryption is necessary for securing video information from unauthorized users. To achieve this, an enhanced video encryption scheme has been proposed in this work which adopts two techniques such as confusion and diffusion. Sundarapandian–Pehlivan chaotic system (Akgul et al. Optik (Stuttg). 127:5491–5499 (2016), [9]) has been adopted as a keystream generator to accomplish the encryption process. This 3D chaotic system has been realized by RungeKutta fourth-order method through which the differential system has been modelled as a discrete system. LabVIEW 2013 environment has been used to develop the proposed cryptosystem in which the camera module has been interfaced to capture the real-time video. This scheme achieves maximum entropy of 7.94627514 and near-zero correlation for a test video which has 141 encrypted frames. Further, NIST SP 800-22 batteries of test has been carried out to ensure the statistical efficiency.
