"数字图像加密关键技术研究与实现：基础、算法、评估"

"Research and Implementation of Key Techniques in Digital Image Encryption" is a bachelor's thesis of 10,000 words, written by a student majoring in Computer Science and Technology at Southwest University of Finance and Economics. The thesis is guided by Professor Niu Honghong. The thesis is divided into six chapters, starting with an introduction that discusses the background, significance, and purpose of the research. Chapter two explores the basics of digital image encryption, including an overview of encryption, traditional encryption algorithms, and the classification of digital image encryption techniques. In chapter three, the focus shifts to the key techniques in digital image encryption, encompassing image data preprocessing, design and implementation of encryption algorithms, and the evaluation of encryption metrics and performance analysis. Chapter four delves into the practical application of digital image encryption, covering the experimental environment, dataset, and the design and analysis of the experiments conducted. The evaluation of the performance of digital image encryption is the main content of chapter five, which includes an assessment of encryption security, efficiency, and a comparison of different encryption algorithms to guide their selection and use. Finally, chapter six presents the conclusions drawn from the research and offers insights into future research directions. The thesis aims at providing a comprehensive understanding of digital image encryption, exploring its key techniques, evaluating its performance, and offering suggestions for future research. It is a valuable contribution to the field of computer science and technology, and it provides a solid foundation for further research and development in digital image encryption.
