A novel one-dimensional sine powered chaotic map and its application in a new image encryption scheme

With the rapid growth of data transmission technology, image encryption is becoming a widely discussed topic in the field of information security. In this paper, we introduce a novel one-dimensional sine powered chaotic system (1DSP). Evaluation of the proposed chaotic system indicates the existence of chaotic behavior with high sensitivity and randomness. We further present a new image encryption scheme using 1DSP (1DSP-IE). The proposed scheme uses the 1DSP for sequence addition to improve its security. Furthermore, row-by-row and column-by-column concepts are used for confusion and diffusion operations. This approach breaks the correlation of adjacent pixels by scrambling pixels out of their original rows and columns and applies bit-level pixel value manipulation for each row and then each column to spread any change in the plain image throughout the ciphered image. The simulation results of the proposed 1DSP-IE indicate an effective encryption and decryption process with good speed. In addition, the security analysis illustrates the ability of 1DSP-IE to provide a satisfying level of security in comparison with other image encryption schemes. (c) 2020 Elsevier Inc.
