A Novel Color Image Encryption Algorithm Based on Hyperchaotic Maps and Mitochondrial DNA Sequences

Multimedia encryption innovation is one of the primary ways of securely and privately guaranteeing the security of media transmission. There are many advantages when utilizing the attributes of chaos, for example, arbitrariness, consistency, ergodicity, and initial condition affectability, for any covert multimedia transmission. Additionally, many more benefits can be introduced with the exceptional space compliance, unique information, and processing capability of real mitochondrial deoxyribonucleic acid (mtDNA). In this article, color image encryption employs a confusion process based on a hybrid chaotic map, first to split each channel of color images into n-clusters; then to create global shuffling over the whole image; and finally, to apply intrapixel shuffling in each cluster, which results in very disordered pixels in the encrypted image. Then, it utilizes the rationale of human mitochondrial genome mtDNA to diffuse the previously confused pixel values. Hypothetical examination and trial results demonstrate that the anticipated scheme exhibits outstanding encryption, as well as successfully opposes chosen/known plain text, statistical, and differential attacks.

Video Encryption Based on Chaotic System and Stream Cipher

the huge development and use of digital multimedia (video, image) over computer networks has led to increase the need for securing of these digital data. Video encryption is widely used as a method for providing security for digital video. In this paper video encryption method is developed using chaotic system for key generator and stream cipher, it uses chaotic map as one-time key generator which produce key used for encryption process. Chaotic systems have been successfully used for multimedia encryption. Chaotic cryptography have good characteristic such as pseudo-randomness, and sensitivity to initial conditions. Video encryption method have successfully designed and implemented, the tests and analysis results have showed the succeed of the encryption method in term of speed and security.

A Novel Hybrid Encryption Method for Multimedia Encryption Using Elliptic Curve Cryptography and TDMRC

We are in the era of digital revolution and the benefits are remarkable. People are much dependent on digital technology and can’t survive without it. With the advancement of Internet and its applications, we share a wide range of data including texts, images, audios and videos in a more extensive space and time scope that we never had before. This increases the need for security day by day. Cryptography is an art of Science that uses complex logic in order to design powerful encryption techniques. Both symmetric and asymmetric key encryptions have their own advantages. Time Dependant Multiple Random Cipher(TDMRC) code is one of the best symmetric encryption schemes. Elliptic curve cryptography(ECC) is widely used because of its less key size and faster key generation. This paper proposes a new method of hybrid encryption method using ECC and TDMRC.
