TLDR
An attempt has been made to review the aspects and approaches of the design used for image encryption.Abstract:
As the exchange of data over the open networks and Internet is rapidly growing, security of the data becomes a major concern. One possible solution to this problem is to encrypt the data. The data can be text, image, audio, video etc.. In today's world most of the multimedia applications involve images. Earlier image encryption techniques like AES,DES,RSA etc. exhibit low levels of security and also weak anti attack ability. This problem was overcome by using chaos based cryptography. The chaotic systems are very sensitive to initial conditions and control parameters which make them suitable for image encryption. Many works have been done in the field of chaos based image encryption. In this survey paper an attempt has been made to review the aspects and approaches of the design used for image encryption.read more

Yang Liu,Xiaojun Tong +1 more
TL;DR: A new hyperchaotic system with bigger Lyapunov exponent is constructed and the self-shrinking generator, which is superior to many other linear feedback shift register-based generators, is used to perturb the hyperchaotics to decrease the period degeneration and improve the performance of the sequences.

A New Chaotic Algorithm for Image Encryption and Decryption of Digital Color Images
TL;DR: A new image encryption scheme which employs one of the three dynamic chaotic systems (Lorenz or Chen or LU chaotic system selected based on 16-byte key) to shuffle the position of the image pixels and uses another one the same three chaotic maps to confuse the relationship between the cipher image and the plain-image thereby significantly increasing the resistance to attacks.
