Summary This paper proposed a hardware architecture of a strong block‐cipher system dedicated to digital image encryption and decryption. On the one hand, a pseudorandom number generator (PRNG) based on two 3D chaotic systems is created to produce strong keys. On the other hand, a robust algorithm is proposed to ensure high‐level security and low computational complexity of image encryption. The algorithm performs image encryption mainly through three processes: pixel values hiding by applying the XOR operation with a key, pixel positions hiding by operating random permutation, and pixel substitution using the S‐box method. To increase the complexity, R rounds of encryption could be accomplished in a loop. Then as a final step, using the Xilinx Vivado/system generator tool, the hardware cryptosystem is developed, implemented, and evaluated on an FPGA‐Zynq evaluation board. According to the synthesis results, the suggested hardware system performs on a reduced FPGA area and gives a good frequency of 156.813 MHz with a high throughput of 20,072.064 Mbps. Several tools and tests utilizing various images are used to evaluate and analyze the hardware cryptosystem. The experimental results show that the hardware implementation has higher performance compared to other recent works.

Differently from the previous studies [9][10][11][12][13][14][15][16][17][18][19][20][21][22] on encryption technique, the algorithm of XOR operation for sequential bits of the pixel has been suggested.

A novel image steganography technique in order to hide the ciphered voice data has been suggested in this work. The doctor's voice comments belonging to a coronavirus disease 2019 (COVID-19) patient are hidden in a medical image in order to protect the patient information. The introduced steganography technique is based on chaos theory. Firstly, the voice comments of the doctor are converted to an image and secondly, they are ciphered utilizing the suggested encryption algorithm based on a chaotic system. Then, they are embedded into the cover medical image. A lung angiography dual-energy computed tomography (CT) scan of a COVID-19 patient is used as a cover object. Numerical and security analyses of steganography method have been performed in MATLAB environment. The similarity metrics are calculated for R, G, B components of cover image and stego image as visual quality analysis metrics to examine the performance of the introduced steganography procedure. For a 512 9 512 pixel cover image, SSIM values are obtained as 0.8337, 0.7926, and 0.9273 for R, G, B components, respectively. Moreover, security analyses which are differential attack, histogram, information entropy, correlation of neighboring pixels and the initial condition sensitivity are carried out. The information entropy is calculated as 7.9993 bits utilizing the suggested steganography scheme. The mean value of the ten UACI and NPCR values are obtained as 33.5688% and 99.8069%, respectively. The results of security analysis have revealed that the presented steganography procedure is able to resist statistical attacks and the chaotic system-based steganography scheme shows the characteristics of the sensitive dependence on the initial condition and the secret key. The proposed steganography method which is based on a chaotic system has superior performance in terms of being robust against differential attack and hiding encrypted voice comments of the doctor. Moreover, the introduced algorithm is also resistant against exhaustive, known plaintext, and chosen plaintext attacks.

“…Although change-point detection is practical and has been widely used in many fields, it hardly meets real-time detection in the autonomous where need to achieve high-performance. [14][15][16] Hence the hardware implementation of change-point detection is essential. Field-programmable gate array (FPGA) has design flexibility due to its reconfigurable nature and has the advantage of a short design cycle compared with the application-specific integrated circuit (ASIC).…”

The mutual interference between frequency modulated continuous wave (FMCW) radars seriously affects autonomous driving. The interference will cause a short-duration pulse-like signal, which contains several change points in the time domain. The change-point detection method called bottom-up segmentation (BOTUP) is applied to deal with a short duration pulse-like signal, which has excellent detection accuracy. However, the serial processing of BOTUP will cause considerable delay, which is not conducive to real-time detection of automatic driving. In this paper, an accelerated architecture of BOTUP (ACC-BOTUP) based on field-programmable gate array (FPGA) is proposed. As BOTUP has segmented characteristics and without data dependency between the cost functions, a parallel structure is proposed to reduce the latency. Further, a pipeline structure is proposed to execute the operations of the cost functions in an overlapping manner. Compared with the original BOTUP (O-BOTUP), the latency of ACC-BOTUP is reduced by 82%, which is more suitable for real-time detection in autonomous driving.
