{"title":"Digital Image Encryption Scheme using Chaotic Sequences with a Nonlinear Function","authors":"H. Ogras, M. Turk","volume":67,"journal":"International Journal of Information and Communication Engineering","pagesStart":885,"pagesEnd":889,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/9005","abstract":"In this study, a system of encryption based on chaotic\nsequences is described. The system is used for encrypting digital\nimage data for the purpose of secure image transmission. An image\nsecure communication scheme based on Logistic map chaotic\nsequences with a nonlinear function is proposed in this paper.\nEncryption and decryption keys are obtained by one-dimensional\nLogistic map that generates secret key for the input of the nonlinear\nfunction. Receiver can recover the information using the received\nsignal and identical key sequences through the inverse system\ntechnique. The results of computer simulations indicate that the\ntransmitted source image can be correctly and reliably recovered by\nusing proposed scheme even under the noisy channel. The\nperformance of the system will be discussed through evaluating the\nquality of recovered image with and without channel noise.","references":"[1] M. P. Kennedy, and G.
