Abstract With the proliferation of information and communication technology in rural areas, e‐commerce has gradually become a new economic phenomenon China. Using national comprehensive demonstration policy as quasi‐natural experiment, this study examines causal linkage between county‐level development Its findings, which draw on panel data from 2011 to 2018, indicate that had positive effect economy China, resulting an overall increase county GDP by 3.5 percent (0.7 annually). Our analysis...
Current image encryption methods have many shortcomings for the medical with high resolution, strong correlation and large storage space, it is difficult to obtain reliable clinically applicable images. Therefore, this paper proposes a algorithm based on new five-dimensional three-leaf chaotic system genetic operation. And dynamic analysis of phase diagram bifurcation selected in carried out, NIST used test randomness its sequence. This follows diffusion-scrambling framework, especially...
The idea of green economy is being taken seriously all over the world. For developing countries, key to strike a balance between environmental protection and economic development. As largest country, China has been exploring scientific schemes deal with relationship Developing rural tourism an important way transform ecological advantages into benefits. However, role remains controversial. No scholars have yet provided solutions for village-level practices in countries from perspective...
To ensure the safe and reliable transmission of images on public channels, this paper proposes a dual-domain image encryption algorithm based hyperchaos dynamic wavelet decomposition. The combination decomposition scrambling diffusion operations is adopted in our to realize spatial frequency domain encryption. This not only ensures security algorithm, but also robustness operating efficiency encryption, at same time reduces risk being attacked. First, divide original into blocks, use random...
In order to improve the security of image transmission, this paper proposes a self-adaptive encryption scheme based on chaos and gravitation model. The proposed consists three stages: key generation stage, double scrambling diffusion stage. plaintext-associated mechanism (BPPAKG) bit plane is used obtain associated with plaintext. Since ultimately depends plaintext itself, has self-adaptability. first stage uses mixed chaotic transform shift row disturb pixel position, then changes value...
Abstract In order to ensure the safe and reliable transmission of images on public channels, this paper proposes a dual-domain image encryption algorithm based seven-dimensional hyperchaos dynamic wavelet decomposition. It is worth mentioning that existing algorithms generally use spatial encryption, which still has shortcomings in security execution efficiency. However, combination decomposition scrambling diffusion operations adopted our realize frequency domain encryption. Compared with...
