Abstract:In this paper, a novel image encryption scheme is proposed for the secure transmission of image data. A self-synchronous chaotic stream cipher is designed with the purpose of resisting active attack and ensures the limited error propagation of image data. Two-dimensional discrete wavelet transform and Arnold mapping are used to scramble the pixel value of the original image. A four-dimensional hyperchaotic system with four positive Lyapunov exponents serve as the chaotic sequence generator of the self-synchronous stream cipher in order to enhance the security and complexity of the image encryption system. Finally, the simulation experiment results show that this image encryption scheme is both reliable and secure.

“…Xiangjun Wu et al proposed a new robust color image encryption scheme based on multiple improved 1D chaotic system and DNA sequence operations [10]. Ali Soleymani et al used the Arnold CAT and Henon chaotic maps for securing images in order to create secret images and by using specific parameters for the permutation [11]. Recently, Zhi Li et al used piecewise linear chaotic maps to encrypt a bit-level image [12].…”

Arnold's CAT Map (ACM) is a chaotic transformation of the 2-dimensional toral automorphism T 2 defined by the mapping Γ ∶ T 2 → T 2 . There are many applications of ACM in various research areas such as: steganography, encryption of images, texts and watermarks. The transformation of an image is achieved by the randomized order of pixels. After a finite number of repetitions of the transformation, the original image reappears. In this study, encryption of two images is demonstrated together with a proposed algorithm. Moreover, the periodicity of ACM is discussed and an algorithm to change the period of ACM is suggested. The resultant period obtained from the new algorithm is compared with the period obtained from the usual ACM. The results show that the period of the proposed algorithm grows exponentially while the period of ACM has an upper bound.

Due to internet explosion there has been considerable rise in transmission of data such as tex videos, etc over internet. Here security is required for transmission of data over internet so that data is secure from sender to receiver. Image Encryption plays an important role for image transmission over the Internet and using chaos system prove more secure than existing traditional cryptographic algorithms like AES, RC5, etc. With Image Encryption it becomes difficult to analyze the image that is communicated over untrusted network.. The paper provides an introduction to Chaos system a encryption as well decryption of images using confusion and diffusion methods achieved by arnold cat map and chen respectively. Comparison with existing algorithms is also done.
