Abstract
In the recent era, data security is important for multimedia communication such as image and video. Secured communication and confidentiality of data play an important role in many online services like authentication, video conferencing, online classes, etc. In this paper, a video encryption technique using improved logistic map and DNA sequencing has been proposed to encrypt the video. The proposed video encryption technique has mainly three phases, firstly key is generated using SHA-256. Second, permutation of the video frame is completed using improved logistic map and SHA-256. In the third step, diffusion on permuted video frame is performed using SHA-256 key and DNA sequencing. Efficiency of the encryption technique is measured through PSNR, entropy, correlation coefficients and NPCR. The presented encryption technique is resistant to the brute force and statistical attack.
