Summary Confidentiality of information must be maintained when it is required to be transmitted over a communication channel or when it is stored in a computer for further information access. Establishing a highly reliable and secure means of wireless communication for the transfer of digital data (text, images, audio, and video) from source to destination is becoming a prime requirement in present‐day wireless communications. Security can be achieved at the network level as well as at the data level. Data‐level security is made through cryptographic techniques. This paper emphasizes data‐level security aspects in a wireless communication system for the secure transmission of images over an AWGN channel condition. Here, a crypto orthogonal frequency division multiplexing system (crypto‐OFDM system) is designed using Rubik's cube encryption algorithm scheme for secured transmission of images under the MATLAB environment. The quality of the image transmission is analyzed using peak signal to noise ratio (PSNR) and BER at different SNR conditions. The quality of the encryption algorithm was also tested with statistical metrics, which are the histogram, NPCR, UACI, entropy, correlation coefficient analysis, etc. The numerical results reveal that a DCT‐based crypto‐OFDM system with Rubik's cube algorithm show a better performance over earlier cryptosystems and also perform superior to the original/basic OFDM system. The statistical analysis tests prove that Rubik's cube algorithm is one of the most robust algorithms for security point of view and is easy to implement, as Rubik's cube algorithm makes use of natural characteristics of pixel values, which form the basis for designing the secret key.

The single-carrier frequency division multiple access (SC-FDMA) is a promising technique that has been adopted as an uplink transmission scheme in the long-term evolution (LTE) cellular system. This is attributed to its advantages such as the low peak-to-average power ratio (PAPR) and the utilization of frequency-domain equalizers to resolve the problem of inter-symbol interference (ISI). In this paper, a Discrete Wavelet Transform (DWT) based SC-FDMA system is proposed for the effective transmission of encrypted images. The 2D Chaotic baker map encryption algorithm has been used to encrypt images to enhance their security during transmission via SC-FDMA- based systems. The performance of the process of encrypted image transmission using the 2D Chaotic baker map algorithm with wavelet transform-based SC-FDMA (DWT SC-FDMA) system is evaluated in terms of different performance metrics, with comparison to Discrete Fourier Transform SC-FDMA (DFT SC-FDMA) and, Discrete Cosine Transform SC-FDMA (DCT SC-FDMA) systems. The viability of the proposed scheme was tested with different wireless channel models and different subcarriers mapping schemes. Experimental results show that the proposed method of the encrypted image transmission via the DWT SC-FDMA system provides a remarkable performance gain compared to the other versions of the SC-FDMA system in terms of the PSNR, and the BER metrics in the wireless channel models. It also demonstrates the effectiveness of the proposed scheme and adds a degree of encryption to the transmitted images through the wireless channels.

Summary Long‐term evolution (LTE) system adopts single‐carrier frequency division multiple access (SC‐FDMA) technique for high data‐rate uplink wireless communication mainly due to its advantage of high power efficiency and low peak‐to‐average‐power ratio (PAPR). This paper presents a chaotic interleaving scheme for the discrete wavelet transform‐based SC‐FDMA (DWT SC‐FDMA) system to improve the transmission quality of images. This interleaving process is‐ based on applying the chaotic Baker map to the image before transmission. The proposed scheme combines the advantages of excellent orthogonality and spectral containment from DWT SC‐FDMA and performances enhancement from chaotic interleaving. The performances evaluation of the DWT‐SC‐FDMA system with the chaotic interleaving scheme for efficient image transmission is studied and compared with two schemes of SC‐FDMA‐based systems: discrete Fourier transform SC‐FDMA (DFT SC‐FDMA) and discrete cosine transform SC‐FDMA (DCT SC‐FDMA) over different wireless channel and subcarriers mapping modes. This comparison aims to select the most suitable structure of SC‐FDMA for the efficient transmission of the images. The obtained results demonstrate the efficiency of the proposed scheme, which gives an improvement of peak signal‐to‐noise ratio (PSNR) of about 36 dB (at SNR = 8 dB) is the case of SUI‐3 channel and a significant enhancement in bit‐error‐ratio (BER) performance.
